As a part of making an application I had a task ahead of renaming 5000 odd pdf's(Question Papers) according to the subject number of the format "AA10001" somewhere mentioned inside the paper. That is when I chose to write a script rather than do it manually.This script here used a bit of regex and os,shutil libraries got the task done. At the end of the day 4400 were renamed successfully while others where exceptions like handwritten or scanned copies. Python \m/P.S: I am not that good at coding ! So do not comment "yuck" on seeing my code :Pimport sys,re,os,shutil from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter from pdfminer.pdfpage import PDFPage from pdfminer.converter import XMLConverter, HTMLConverter, TextConverter from pdfminer.layout import LAParams from cStringIO import StringIO       def pdfparser(data,filed):  fp = file(pat, 'rb')  rsrcmgr = PDFResourceManager()  retstr = StringIO()  codec = 'utf-8'  laparams = LAParams()  device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)  # Create a PDF interpreter object.  interpreter = PDFPageInterpreter(rsrcmgr, device)  # Process each page contained in the document.    for page in PDFPage.get_pages(fp):  interpreter.process_page(page)  data = retstr.getvalue()  pattern = re.compile('[A-Z]{2}\s*\d{5}')  match = re.search(pattern, data)  try:  s=match.start()  e=match.end()  return data[s:e].replace(' ','')  except:  return False   if __name__ == '__main__':  Arry=range(2011,2012)  for xi in Arry:  rootdir="#path"#+str(xi)+"/"  count_rename=0  count_bad=0  for root,dirsa,files in os.walk(rootdir):  for name in files:  pat=os.path.join(root,name)  head,tail=os.path.split(pat)  if name.endswith(".pdf"):  print name  rep = pdfparser(sys.argv[0],name)  if rep:  print rep  os.rename(pat,head+"/"+rep+".pdf")  count_rename+=1  else:  try:  count_bad+=1  print "Bad File"   #shutil.move(pat,"#path"+str(xi)+"/")  except:  pass  print count_rename  print count_bad  

This question deserves a lengthy answer beyond the scope of Quora. Let me know if it gets annoying. Send me edits to reduce the content.Better way to change directory:If you are a command-line user, autojump is a must have package. You can change directory by just specifying a part of directory name (without subdirs). You can also use jumpstat to get a statistics of your directory jumps.$ j log/var/log$ j ard/home/ab/work/arduinoFree up disk space:bleachbit is a neat utility to find and remove files based on application specific knowledge. Few more useful tools: localepurge, deborphan/orphaner, computer-janitor-gtk.Undelete for console: Save frustration.libtrash provides trashcan/recycle-bin like functionality for console users. Also look at e2undel, recover, recoverjpeg tools.Sys-admin friendly relatively unknown tools:dstat,htop, iotopethtool, mii-tooldmidecodelsof, netstat -ntfreeipmiRun level editor: Save some boot time.rcconf: Cursed based tool for Debian, Ubuntu and clonesntsysv: Curses based tool for Red Hat and cloneschkconfig: Command line tool for Red Hat and clonessystemctl: Newer command line tool for Red Hat and clonesupdate-rc.d: Command line tool for Debian, Ubuntu and clonesPackage search:Find which package this path/file belongs to:dpkg -S /path/to/filerpm -qf /path/to/filerpm -qa, apt-file are additional useful commands to take a look at.X Windows - Launch Application as other user:$ xhost +local:$ su - otheruser$ export DISPLAY=:0.0$ xeyesEmail Backup:offlineimap for imap users.Display blanking:Blank display:$ xset -display :0 dpms force standbyEnable / Disable screen sleep:xset s on; xset +dpmsxset s off; xset -dpmsManual CPU Frequency ScalingAdd these aliases to your .bashrcalias cpupowersave='sudo cpupower frequency-set -g powersave'alias cpuconservative='sudo cpupower frequency-set -g conservative'alias cpuondemand='sudo cpupower frequency-set -g ondemand'alias cpuperformance='sudo cpupower frequency-set -g performance'alias freqinfo='cpupower frequency-info'alias freqlist='cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors'cputemperature(){ awk '{ print("Temperature: "$2"°F");}' < /proc/acpi/ibm/thermal; }Lenovo / Thinkpad Manual FAN ControlTo enable manual fan control, run this command once.$ echo "options thinkpad_acpi fan_control=1" > /etc/modprobe.d/thinkpad_acpi.conf$ rmmod thinkpad_acpi; modprobe thinkpad_acpiThen add these aliases to your .bashrc. "fan-disengaged" command will unleash the fan to max speed. I use it to rapidly cool down my CPU when it gets too hot watching video or caught inside my blanket.alias fan-off='sudo bash -c "echo level 0 > /proc/acpi/ibm/fan"'alias fan-low='sudo bash -c "echo level 2 > /proc/acpi/ibm/fan"'alias fan-med='sudo bash -c "echo level 4 > /proc/acpi/ibm/fan"'alias fan-max='sudo bash -c "echo level 7 > /proc/acpi/ibm/fan"'alias fan-auto='sudo bash -c "echo level auto > /proc/acpi/ibm/fan"'alias fan-disengaged='sudo bash -c "echo level disengaged > /proc/acpi/ibm/fan"' ## disengaging may damage your fan over frequent useMute / Unmute Sound:$ amixer set Master on|offWireless network listing:$iwlist INTERFACE scanEg. $ iwlist wlan0 scan | grep ESSIDReplace strings across multiple files:sed -i 's/OLD/NEW/g' *.txtIf you are allergic to regex, you can use less powerful 'replaceit' tool.Reverse SSH:It is useful, when you want to let some one from outside world to SSH into your firewall protected local network (with no public IP). Use it with caution.SSH from local laptop to remote host:$ ssh -C -g -R :$REM-PORT:127.0.0.1:22 $REM-HOSTNow from any where, if you ssh to REMOTE-HOST:REMOTE-PORT, you will get connected to the local network (say from office to your laptop connected to home network).$ ssh $REM-HOST -p $REM-PORTDirectory commands for console users:pushd . push current dir to stack. You can push multiple dirs.popd chdir to top of stack.cd - chdir to previous dir.Also take a look at wcd and autojump, You can change to dir based on file names, matching patterns or bookmarks.Editing with Readline keys:Readline library provides GNU Emacs or Vi like key bindings. Number of packages such as GNU bash and ncftp uses libreadline for CLI and auto-completion. You can do amazing stunts with readline interface if you remember few GNU Emacs of Vi key strokes.I am only going to list GNU Emacs key strokes here.. Vi mode will probably slow you down. No vi bashing ;)Basic:Ctrl+a Go to beginning of line.Ctrl+e Go to end of lineCtrl+f Go right one character.Ctrl+b Go left one character.Ctrl+p Go to previous line ("up") (only works in multiline text areas).Ctrl+n Go to next line ("down") (only works in multiline text areas).Ctrl+k Delete to end of lineCtrl+y pastes from buffer.Ctrl+u Delete entire lineCtrl+w Delete word, left.Ctrl+h Delete character, left (backspace).Ctrl+d Delete character, right.Ctrl+_ Undo.Ctrl+t Char swap.Ctrl+c CancelAdvanced Key Strokes:Alt+. Last word of previous command. You can hit multiple times.Alt+u/d/c Up case / Down case / Capitalize.Ctrl+r Reverse history search.Alt+{ Auto complete wild-card expr of current dir contentsAlt+</> (<) Beginning, (>)end of history.Alt+NUM Repeat command. Eg: Alt+13 followed by 'e' prints 13 'e's. You can prefix commands too. Alt+4, Ctr+d deletes 4 chars forward. Alt+4, Ctrl+h deletes 4 chars backwards. Fun part is, you can use negative numbers. Alt+-4, Ctrl+d deletes 4 chars backwards (negative commands).Also uncomment the following in your .bashrc. It will enable context sensitive auto-completionif [ -f /etc/bash_completion ] && ! shopt -oq posix; then  . /etc/bash_completion fi Add these lines to your ~/.bashrc for pdfinvert command. Rotates PDF documents in place to 180 degrees. You must have installed pdftk package.pdfinvert(){if [ -z "$1" ]; thenecho "Usage: pdfinvert FILE.PDF"elsepdftk "$1" cat 1-endD output "$1.bak" && \mv -f "$1.bak" "$1"fi}Readline even has a startup file. It is pretty powerful. Follow the URL:http://cnswww.cns.cwru.edu/php/chet/readline/rluserman.htmlReadline for Gnome / GTK based applications:If you are using Gnome desktop, try this command. All GTK+ applications will respond to your GNU Emacs key strokes. gconftool-2 permanently adds this setting to your Gnome configuration database (registry). Changes are applied instantly without requiring any application restart.$ gconftool-2 --set /desktop/gnome/interface/gtk_key_theme Emacs --type stringReadline for Python Interpreter:You can activate readline inside python interpreter and tab-complete function calls. You can also try "bpython" or "ipython" alternatively.$ python>>> import rlcompleter, readline>>> readline.parse_and_bind('tab: complete')Readline for GNU Guile Interpreter:You can activate readline inside guile interpreter and tab-complete function calls.$ guileguile> (use-modules (ice-9 readline))guile> (activate-readline)Readline for Ruby Interpreter:You can activate readline inside Ruby interpreter and tab-complete function calls.$ irbirb(main):001:0> require 'irb/completion'=> trueReadline for APT package management:Install readline capable interactive APT shell on Debian, Ubuntu and clones.$ apt-get install aptsh$ aptshRelatively Unknown GNU Emacs Tricks:GNU Emacs is an operating system on its own. Listing emacs treasures will be endless.Rectangular cut-copy: C-DEL - mark region, C-x r k - cut rectangular region, C-x r y - insert rectangular region.C-h b - describe key bindings and its functions specific to current mode.ANY-PARTIAL-KEY-BINDINGS, C-h - Describes possible completions. For example try, C-x r, C-h.C-h f - describe emacs function.M-x apropos-command - List config options for commands matching approximately.C-x C-e - evaluate expression preceding point within a buffer.C-M-x - evaluate expression at point.Try evaluating this string '(+ 99 24 444)'M-x flyspell-buffer - on the fly spell checking.M-x global-font-lock-mode - toggle syntax coloring.M-x wdired-change-to-wdired-mode - When you are in directory listing mode, try this command. You will be able to edit file and dir names like text. Even find and replace them. When you are done, simply C-x C-s to apply changes. I use this feature to bulk edit music file names in combination with id3tool..emacs startup file: following variables let Emacs manage backup files under a custom directory.(custom-set-variables'(backup-by-copying t)'(backup-by-copying-when-linked t)'(backup-directory-alist (quote ((".*" . "~/.emacs-backup"))))'(delete-old-versions t))(menu-bar-mode nil) ;; saves menu bar space(display-time-mode) ;; displays time always in status barIf nothing works, at least remember C-x, C-c to gracefully shutdown GNU Emacs ;-).

First of all, I would like to apologize for the upcoming writing mistakes,There had been times when I was low but one of them was worst.I have been preparing for banking exams since June 2018, starting with SBI PO which I failed in mains,Quite a close … 2 marks more and I would have given an interview…Somewhere in October month,As I have made my mind to give only PO exams and nothing else… this time I was comfortable since I have cleared SBI PO pre in first attempt and people around me were more confident about my success.. so I thought it is almost done. However this time I also filled IBPS clerk which I failed miserably in pre by 0.25.Meanwhile, I filled NIACL AO and got the same treatment failed in pre by a big margin, but I wasn’t sad since I was waiting for my final result.then here comes the doom day for which I waited for around 5 months IBPS PO Final result and you can predict the outcome - “Fail”.The final cutoff was around 43.xx and I got somewhere around 40.I was broken for a day or two, but now I knew that I am more close than ever. So I started again from the beginning, practicing and revising all quant concepts, giving time to English and also started solving big puzzles.Now I was in the comfort zone, I filled SBI PO 2nd time, also gave LIC AAO in between which I failed cause I was more focused on SBi, I never wanted to be a LICian, so finally gave SBI PO pre-cleared then mains cleared and then interview… was not 100% sure about my success but still had faith.D-day 18/10/2019This day was as normal as any other day until 7 pm when I got the news that result came and I picked up my lappy started searching for any random website which will take me to the final result pdf, I downloaded it put my roll no. in the search section.The result - No result foundI tried again and thought about going manually but it wasn’t there, I couldn’t feel what was happening, my friends started asking me about the result, some were sharing their happy moments but I was lost in my mind.Tears came first time so brutally like they do not want to stay more in that confined space… I tried to stop myself but all my hearted wanted is to cry out loud and I did it inside the blanket, I told my family and they were shocked too. Since I don't want to hurt them so I kept my face as nothing big happened. When you lose after getting this much close it hurts, because all I wanted is to crack SBI PO, I started my whole preparation for that exam only.But life is not all about failures, just failure makes success more lucrative.After 10 days I got my first success selected as SBI Junior Associate, this wasn’t my moment but it did make me happy.My roll no. is somewhere there :p,On 22nd Nov 2019, I got my second job selected as ASO in EPFOThe first one in the row… I was sleeping and my friend called and congratulated me, which I didn't believe so I searched my name in the pdf and shocked after seeing my name on the list.On 1 Jan 2020 got 3rd job selected as RRB POFinally on 16th Jan selected as LIC AssistantThe one thing I am proud of is my confidence and trust in my knowledge, from day 1, I knew that sooner or later I will succeed.So yes this is my Journey from low to steady,you can ask me questions about preparation though I’m just learning.Sorry for keeping this long, I will update it further.Dasvidaniya.
