Create a tar archive using xz compression

Compress files or a directory to xz format. XZ has superior and faster compression than bzip2 in most cases. XZ is superior to 7zip format because it can save file permissions and other metadata data.

have tar decide compression based on filename

the -a flag causes tar to automatically pick the right compressor to filter the archive through, based on the file extension. e.g. "tar -xaf archive.tar.xz" is equivalent to "tar -xJf archive.tar.xz" "tar -xaf archive.tar.gz" is equivalent to "tar -xzf archive.tar.gz" No need to remember -z is gzip, -j is bzip2, -Z is .Z, -J is xz, and so on :)

Parallel XZ with progress bar

You need: pxz for the actual work (http://jnovy.fedorapeople.org/pxz/). The function could be better with better multifile and stdin/out support.
This is sample output - yours may be different.

function xzv() { THREADS=`grep processor /proc/cpuinfo | wc -l`; for file in $*; do pv -s `stat -c%s $file` < $file | pxz -q -T $THREADS > $file.xz ; done; }

Chronometer in hour format

Shorter and faster...

Random quote from Borat

I improved a bit on the original by only using sed and extracting the quote with a matching group. Use -nE for sed on Mac OSX Use -nr for sed on Linux. Warning! The quotes from Borat are definitely offensive.

Grep Recursively Through Single File Extension

Trac 0.12.2-stable

Rapidly invoke an editor to write a long, complex, or tricky command

Next time you are using your shell, try typing ctrl-x e (that is holding control key press x and then e). The shell will take what you've written on the command line thus far and paste it into the editor specified by $EDITOR. Then you can edit at leisure using all the powerful macros and commands of vi, emacs, nano, or whatever.

which procs have $PATH_REGEX open?

faster than lsof by at least x2 on my box.

print all network interfaces' names and IPv4 addresses

ifconfig can't properly display interface's name longer 9 symbols,also it can't show IPs added thru ip command, so 'ip' should be used instead. This alias properly shows long names, bond interfaces and all interface aliases. loopback interface is ignored, since its IP is obvious

Encrypt and password-protect execution of any bash script

(Please see sample output for usage) script.bash is your script, which will be crypted to script.secure script.bash --> script.secure You can execute script.secure only if you know the password. If you die, your script dies with you. If you modify the startup line, be careful with the offset calculation of the crypted block (the XX string). Not difficult to make script editable (an offset-dd piped to a gpg -d piped to a vim - piped to a gpg -c directed to script.new ), but not enough space to do it on a one liner.

copy hybrid iso images to USB key for booting from it, progress bar and remaining time are displayed while copying

GZip all files in a directory separately

Coping files, excluding certain files

Preserve file structure when coping and exclude some file o dir patterns
