Copy your ssh public key to a server from a machine that doesn't have ssh-copy-id

Creates the .ssh directory on the remote host with proper permissions, if it doesnt exist. Appends your public key to authorized_keys, and verifies it has proper permissions.

Speed Up WAN File Transfer With Compression

If you have servers on Wide Area Network (WAN), you may experience very long transfer rates due to limited bandwidth and latency. To speed up you transfers you need to compress the data so you will have less to transfer. So the solution is to use a compression tools like gzip or bzip or compress before and after the data transfer. Using ssh "-C" option is not compatible with every ssh version (ssh2 for instance).

avoid ssh hangs using jobs

Execute commands serially on a list of hosts. Each ssh connection is made in the background so that if, after five seconds, it hasn't closed, it will be killed and the script will go on to the next system. Maybe there's an easier way to set a timeout in the ssh options...

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Re-use the previous command output

The $(!!) will expand to the previous command output (by re-running the command), which becomes the parameter of the new command newcommand.

Detect illegal access to kernel space, potentially useful for Meltdown detection

Based on capsule8 agent examples, not rigorously tested

Backticks are evil

This is a simple example of using proper command nesting using $() over ``. There are a number of advantages of $() over backticks. First, they can be easily nested without escapes: $ program1 $(program2 $(program3 $(program4))) versus $ program1 `program2 \`program3 \`program4\`\`` Second, they're easier to read, then trying to decipher the difference between the backtick and the singlequote: `'. The only drawback $() suffers from is lack of total portability. If your script must be portable to the archaic Bourne shell, or old versions of the C-shell or Korn shell, then backticks are appropriate, otherwise, we should all get into the habit of $(). Your future script maintainers will thank you for producing cleaner code.

Parse m3u playlist file for total time

Parse an m3u file with seconds for each item and output the length of the entire playlist

copy partition table from /dev/sda to /dev/sdb

LDAP search to query an ActiveDirectory server

These are the parameters to ldapsearch (from ldap-utils in Ubuntu), for searching for the record for Joe Blogg's user. sAMAccountName is the LDAP field that ActiveDirectory uses to store the user name. 'DOMAIN\Joe.Bloggs' where "DOMAIN" is the the active directory domain. Othewise you could use "CN=Joe.Bloggs,DC=example,DC=com" instead of "DOMAIN\Joe.Bloggs"

get all Google ipv4 subnets for a iptables firewall for example

a bit shorter, parenthesis not needed but added for clarity

list block devices

Shows all block devices in a tree with descruptions of what they are.

print crontab entries for all the users that actually have a crontab

This is how I list the crontab for all the users on a given system that actually have a crontab. You could wrap it with a function block and place it in your .profile or .bashrc for quick access. There's prolly a simpler way to do this. Discuss.
