Check These Out
shell function which allows you to tag files by creating symbolic links directories in a 'tags' folder.
The tag function takes a tag name as its first argument, then a list of files which take that tag. The directory $HOME/tags/tagname will then hold symbolic links to each of the tagged files. This function was modified from bartonski's (http://www.commandlinefu.com/commands/view/10216) inspired by tmsu (found at https://bitbucket.org/oniony/tmsu/wiki/Home) with readlink function by flxndn (http://www.commandlinefu.com/commands/view/10222).
Example:
$ tag dog airedale.txt .shizturc weimeraner.pl
This will create $HOME/tags/dog which contains symbolic links to airedale.txt .shizturc and weimeraner.pl
pgrep, pkill - look up or signal processes based on name and other attributes
While at the command line of of hosta, scp a file from remote hostb to remote hostc. This saves the step of logging into hostb and then issuing the scp command to hostc.
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video).
$ cat /proc/acpi/video/VGA/LCD/brightness
to discover the possible values for your display.
For ipv6 use: grep -oE "\b([0-9A-Fa-f]{1,4}:){7}[0-9A-Fa-f]{1,4}\b"
This is assuming that you're editing some file that has not been wrapped at 80 columns, and you want it to be wrapped. While in Vim, enter ex mode, and set the textwidth to 80 columns:
$ :set textwidth=80
Then, press:
$ gg
to get to the top of the file, and:
$ gqG
to wrap every line from the top to the bottom of the file at 80 characters.
Of course, this will lose any indentation blocks you've setup if typing up some source code, or doing type setting. You can make modifications to this command as needed, as 'gq' is the formatting command you want, then you could send the formatting to a specific line in the file, rather than to the end of the file.
$ gq49G
Will apply the format from your current cursor location to the 49th row. And so on.
This alias is super-handy for me because it quickly shows the details of each file in the current directory. The output is nice because it is sortable, allowing you to expand this basic example to do something amazing like showing you a list of the newest files, the largest files, files with bad perms, etc..
A recursive alias would be:
$ alias LSR='find -mount -printf "%.5m %10M %#9u:%-9g %#5U:%-5G %TF_%TR %CF_%CR %AF_%AR %#15s [%Y] %p\n" 2>/dev/null'
From: http://www.askapache.com/linux/bash_profile-functions-advanced-shell.html
sort -R randomize the list.
head -n1 takes the first.
