Get the PID of a process by name

it is not work with Cygwin's bash3.X. Test in Linux.

use printf "%'f" number while it is floating point number

Very very cool list of quotations and directives on pythonic programming. I love them and they are sure applicable in C++ too, and for most any programming, really.

Tested with NTFS and found on this site:

The first 32256 bytes is the MBR

the command for the impatient sysadmin: simply checks every five secs, if a host or a specific service running on it is up. ideal for hosts that are configured not to respond on pings.

This will email [email protected] a message with the body: "rsync done" when there are no processes of rsync running. This can be changed for other uses by changing $(pgrep rsync) to something else, and echo "rsync done" | mailx [email protected] to another command.

Very helpful when you've got complex filenames and needs to change just some small parts of it.

Renaming a file called "i-made-a-small-typo-right-here" to "i-made-a-big-typo-right-here":

You could also copy multiple files, edit, remove, process, etc.

This will start a netcat process listening on port 666. If you are able connect to your your server, netcat will receive the data being sent and spit it out to the screen (it may look like random garbage, so you might want to redirect it to a file).

no external commands, but can only do 0-99, not 1-100, so we adjust it later

alternative using 'host'

preferred way to query ps for a specific process name (not supported with all flavors of ps, but will work on just about any linux afaik)

You'll first need to install the uuid package. Available immediately from apt in Ubuntu, Debian, or other myriad Debian variants. You could always compile it from source as well.

Best to put it in a file somewhere in your path. (I call the file spath)

#!/bin/bash

IFS=:; find $PATH | grep $1

Usage: $ spath php

watch is a command especially designed for doing this job

This command produces the output of "du -sk testfile" in every 10 seconds. You can change the command to be whatever you want.

I dont have curl or links installed, so I use wget with write file as standard out.
