This will extract all of the urls from a firefox session (including urls in a tab's history). The sessionstore.js file is in ~/.mozilla/firefox/{firefox profile}

egrep -r '(render_message|multipart).*('`find app/views -name '*.erb' | grep mailer | sed -e 's/\..*//' -e 's/.*\///' | uniq | xargs | sed 's/ /|/g'`')' app/models

This expression looks for groups inside of a GroupOfNames class element, that is itself inside one (or many) Organizational Unit (ou) nodes in the ldap tree. Give you a quick dump of all the groups the user belongs to. Handy for displaying on a webpage.

use to execute a block of code only if $var is numeric

Finds all corrupted jpeg files in current directory and its subdirectories. Displays the error or warning found.

The jpeginfo is part of the jpeginfo package in debian.

Should you wish to only get corrupted filenames, use cut to extract them :

find ./ -name *jpg -exec jpeginfo -c {} \; | grep -E "WARNING|ERROR" | cut -d " " -f 1

Lists revisions in a Subversion repository with a timestamp that doesn't follow the revision numbering order. If everything is OK, nothing is displayed.

find /var/log -type f -exec file {} \; | grep 'text' | cut -d' ' -f1 | sed -e's/:$//g' | grep -v '[0-9]$' | xargs tail -f

Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option.

This command line simply take log files which are text files, and not ending with a number, and it will continuously monitor those files.

Putting one alias in .profile will be more useful.

while [ i != 0 ]; do sleep 1 | dialog --clear --gauge "Quality: " 0 0 $(cat /proc/net/wireless | grep $WIRELESSINTERFACE | awk '{print $3}' | tr -d "."); done

The variable WIRELESSINTERFACE indicates your wireless interface

ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
git grep -l "your grep string" | xargs gedit

Note that this assumes the application is an SVN checkout and so we have to throw away all the .svn files before making the substitution.

exported files will get a .r23 extension (where 23 is the revision number)

lsof -nP +p 24073 | grep -i listen | awk '{print $1,$2,$7,$8,$9}'
kill_daemon() { echo "Daemon?"; read dm; kill -15 $(netstat -atulpe | grep $dm | cut -d '/' -f1 | awk '{print $9}') }; alias kd='kill_daemon

Just find out the daemon with $ netstat -atulpe. Then type in his name and he gets the SIGTERM.

will display typedefs, structs, unions and functions declared in 'stdio.h'(checkout _IO_FILE structure). It will be helpful if we want to know what a particular header file will offer to us. Command 'cpp' is GNU's C Preprocessor.

F="$HOME/.moz*/fire*/*/session*.js" ; grep -Go 'entries:\[[^]]*' $F | cut -d[ -f2 | while read A ; do echo $A | sed s/url:/\n/g | tail -1 | cut -d\" -f2; done

Tuned for short command line - you can set the path to sessionstore.js more reliable instead of use asterixes etc.

Usable when you are not at home and really need to get your actual opened tabs on your home computer (via SSH). I am using it from my work if I forgot to bookmark some new interesting webpage, which I have visited at home. Also other way to list tabs when your firefox has crashed (restoring of tabs doesn't work always).

This script includes also tabs which has been closed short time before.

expr $(fdisk -s ` grep ' / ' /etc/mtab |cut -d " " -f1`) / 1024

The curl command retrieve the HTML text containing the IP address. The grep command picks out the IP address from that HTML text.

Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

netstat -ntlp | grep -w 80 | awk '{print $7}' | cut -d/ -f1
find / -iname '*.pdf' -print -exec pdftotext '{}' - \; | grep --color -i "unix"

-l outputs only the file names

-i ignores the case

-r descends into subdirectories

find . -name "*.jar" | while read file; do echo "Processing ${file}"; jar -tvf $file | grep "Foo.class"; done

Replace * with any filename matching glob or an individual filename

This is useful for displaying a portion of a FILE that contains an error at line NUMBER
