Useful to identify the field number in big CSV files with large number of fields. The index is the reference to use in processing with commands like 'cut' or 'awk' involved.

This command run fine on my Ubuntu machine, but on Red Hat I had to change the awk command to `awk '{print $10}'`.

pyt 'Stairway to heaven - Led Zeppelin'

pyt 'brain damage - Pink Floyd'

No web browser or even X needed. Just a cli and internet connection!

mplayer is pauseable and can skip ahead

This may break if youtube changes their search html.

Don't want to open up an editor just to view a bunch of XML files in an easy to read format? Now you can do it from the comfort of your own command line! :-) This creates a new function, xmlpager, which shows an XML file in its entirety, but with the actual content (non-tag text) highlighted. It does this by setting the foreground to color #4 (red) after every tag and resets it before the next tag. (Hint: try `tput bold` as an alternative). I use 'xmlindent' to neatly reflow and indent the text, but, of course, that's optional. If you don't have xmlindent, just replace it with 'cat'. Additionally, this example shows piping into the optional 'less' pager; note the -r option which allows raw escape codes to be passed to the terminal.

It's useful when you cannot access your env (systemd) or the process DISPLAY variable is not set. Perhaps also when you have a multi-head/user configuration.

Sometimes it's useful to output just the ip address. Or some other information, changing the "ipv4.addresses" in command. The power of awk! Show all possible "greps" with

nmcli connection show [yourInterfaceNameHere]

I copied this (let's be honest) somewhere on internet and I just made it as a function ready to be used as alias. It shows the 10 most used commands from history. This seems to be just another "most used commands from history", but hey.. this is a function!!! :D

Working with lists of IP addresses it is sometimes useful to summarize a count of how many times an IP address appears in the file.

This example, summarizeIP, uses another function "verifyIP" previously defined in commandlinefu.com to ensure only valid IP addresses get counted. The summary list is presented in count order starting with highest count.

gets network ports

only ones for the sshd service

only logged in a specific user (changed for public posting)

only in a specific localhost:port range

not IPv6

Only the part of the response after the ":" character

Only the part of the response before the 1st space

Output is just the rssh port

usage = crontest "/path/to/bin"

This version of this function will echo back the entire command so it can be copied/pasted to crontab. Should be able to be automagically appended to crontab with a bit more work. Tested on bash and zsh on linux,freebsd,aix

Outputs Windows Services service name and display name using "sc query", pipes the output to "awk" for processing, then "column" for formatting.

List All Services:

sc query state= all | awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\:

List Started Services:

sc query | awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\:

List Stopped Services:

sc query state= inactive| awk '/SERVICE_NAME/{printf"%s:",$2;getline;gsub(/DISP.*:\ /,"");printf"%s\n",$0}' | column -ts\:
