Print current running shell, PID
works as well as echo $0, but also prints process id, which pts you're using. echo $SHELL doesn't always get updated when changing shells, so this is a better solution than that. Just one more variation on a theme.

Set name of windows in tmux/byobu to hostnames of servers you're connected to
*I run this with byobu as as a custom status bar entry that runs every 10 seconds by putting it in a script here: $ .byobu/bin/10_update_windows There's no output to stdout, so nothing is displayed on the status bar. *Presumes that #{pane_title} is set to the hostname or prompt containing the host name. In my case, it's in this format: $ $USER@$HOSTNAME:$PWD The sed commands may need to be modified if your pane_title is different. *If you want to strip out a common part of a hostname, add the following before '| uniq' $ -e 's/[COMMON PART]//' I use that to strip out the domain of the servers I connect to, leaving the subdomain.

Colorized grep in less
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.

count files by type
displays a list of all file extensions in current directory and how many files there are of each type of extension in ascending order (case insensitive)

Take a screenshot every 2 seconds
Take a screenshot every 2 seconds and save it as a png file

Load file into RAM (cache) for faster accessing for repeated usage

Show crontabs for all users
This is flatcaps tweaked command to make it work on SLES 11.2

get all Amazon cloud (amazonws etc) ipv6 subnets

Capture SMTP / POP3 Email

Show directories in the PATH, one per line
This version uses Pipes, but is easier for the common user to grasp... instead of using sed or some other more complicated method, it uses the tr command
