Convert all Microsoft Word files in current directory to HTML.

Find out the starting directory of a script

I submitted a command like this without $0 if $BASH_SOURCE is unset. Therefor, it did only work when using ./script, not using 'sh script'. This version handles both, and will set $mydir in a script to the current working directory. It also works on linux, osx and probably bsd.

Recursively remove all empty directories

It starts in the current working directory. It removes the empty directory and its ancestors (unless the ancestor contains other elements than the empty directory itself). It will print a failure message for every directory that isn't empty. This command handles correctly directory names containing single or double quotes, spaces or newlines. If you do not want only to remove all the ancestors, just use: find . -empty -type d -print0 | xargs -0 rmdir
This is sample output - yours may be different.

find . -empty -type d -print0 | xargs -0 rmdir -p

Easy IPTables management

These series of commands allows you all at once to make a backup of your current config, edit that config, then saves it as the running config and makes it persistent. I would advise knowing what your doing to the config before running this because if you mess up say the port 22 portion, you may get knocked off the system. ;) Don't say I didn't warn ya!

Simple Bashrc Cron Job Using Aliases For A Simple Interface

Everytime You Run Bash It Will Run And Send The Command To Background In A Loop Forever. This Is Useful In Android To Avoid Getting Discconnected While Using ADB Or Other Services Like SSH By Being Inactive For Long Periods Of Time.

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Get the Volume labels all bitlocker volumes had before being encrypted

Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Find removed files still in use via /proc

Oracle DBA remove some logfiles which are still open by the database and he is complaining the space has not been reclaimed? Use the above command to find out what PID needs to be stopped. Or alternatively recover the file via: $ cp /proc/pid/fd/filehandle /new/file.txt

remove empty lines

write the output of a command to /var/log/user.log... each line will contain $USER, making this easy to grep for.

This command is useful if you want to copy the output of a series of commands to a file, for example if you want to pastebin the output from 'uname -a', 'lspci -vvv' and 'lsmod' for video driver trouble-shooting on your favorite Linux forum. 'log' takes all the following arguments as a command to execute, with STDOUT sent to /var/log/user.log. The command is echoed to the log before it is executed. The advantages of using logger (as opposed to appending output from commands to a file) are 1) commands are always appended to the logs... you don't have to worry about clobbering your log file accidentally by using '>' rather than '>>' 2) logs are automatically cleaned up by logrotate. The following functions allow you to mark the start and end of a section of /var/log/user.log. $ startlog() { export LOGMARK=$(date +%Y.%m.%d_%H:%M:%S); echo "$LOGMARK.START" | logger -t $USER; } then $ endlog() { echo "$LOGMARK.END" | logger -t $USER; } printlog will print all lines between $LOGMARK.START and $LOGMARK.END, removing everything that is prepended to each line by logger. $ printlog() { sudo sed -n -e "/$LOGMARK.START/,/$LOGMARK.END/p" /var/log/user.log| sed "s/.*$USER: //"; } The following command should dump just about all the information that you could possibly want about your linux configuration into the clipboard. $ startlog; for cmd in 'uname -a' 'cat /etc/issue' 'dmesg' 'lsusb' 'lspci' 'sudo lshw' 'lsmod'; do log $cmd; done; endlog; printlog | xsel --clipboard This is ready for a trip to http://pastebin.com/, and you don't have to worry about leaving temporary files lying around cluttering up $HOME. Caveats: I'm sure that startlog, endlog, and printlog could use some cleanup and error checking... there are unchecked dependencies between printlog and endlog, as well as between endlog and startlog. It might be useful for 'log' to send stderr to logger as well.
