analyze traffic remotely over ssh w/ wireshark
Please check out my blog article on this for more detail. http://jdubb.net/blog/2009/08/07/monitor-wireshark-capture-real-time-on-remote-host-via-ssh/

Print stack trace of a core file without needing to enter gdb interactively
This does almost the same thing as the original, but it runs the full backtrace for _all_ the threads, which is pretty important when reporting a crash for a multithreaded software, since more often than not, the signal handler is executed in a different thread than the crash happened.

Listing directory content of a directory with a lot of entries
Ever wanted to get the directory content with 'ls' or 'find' and had to wait minutes until something was printed? Perl to the rescue. The one-liner above(redirected to a file) took less than five seconds to run in a directory with more man 2 million files. One can adapt it to e.g. delete files that match a certain pattern.

Insert the last argument of the previous command
for example if you did a: $ ls -la /bin/ls then $ ls !$ is equivalent to doing a $ ls /bin/ls

Find the package that installed a command

Share a 'screen'-session
Ater person A starts his screen-session with `screen`, person B can attach to the srceen of person A with `screen -x`. Good to know, if you need or give support from/to others.

set prompt and terminal title to display hostname, user ID and pwd
used in an if-then-else in case the default shell is ksh, not bash. The $(basename ${0#-}) is handy to echo which shell and strip the dash some flavors put in front of "bash" if [ $(basename ${0#-}) == "bash" ] ; then export PS1='\[\e]0;\h \u \w\a\]\n\[\e[0;34m\]\u@\h \[\e[33m\]\w\[\e[0;32m\]\n\$ ' else HOST=`hostname` ESC=`echo "\033"` BEL=`echo "\007"` RAW=`echo "\r"` export PS1='-${RAW}${ESC}]0;${HOST} ${USER}${BEL}-${ESC}[0;34m${USER}${ESC}[0m@${ESC}[0;34m${HOST%%.*}${ESC}[0;33m${ESC}[0m $ ' fi

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

kill some process (same as others) but parsing to a variable
Kills a process matching program. I suggest using $ pgrep -fl program to avoid over-killings Nice the following: kills all bash process owned by guest $ pkill -9 -f bash -u guest

List all authors of a particular git project
This should work even if the output format changes.
