Check These Out

List .log files open by a pid
Uses lsof to display the full path of ".log" files opened by a specified PID.

Verify MD5SUMS but only print failures
All valid files are withheld so only failures show up. No output, all checks good.

Outputs each arg on its own line
This can be useful for transforming command-line args into input for xargs (one per line). This can also be done with ls if the args are filenames, but that's getting awfully close to Useless Use of Cat territory (http://partmaps.org/era/unix/award.html).

Exclude .svn, .git and other VCS junk for a pristine tarball
~$ tar --version tar (GNU tar) 1.20

Remote copy directories and files through an SSH tunnel host
If you have lots of remote hosts sitting "behind" an ssh proxy host, then there is a special-case use of "rsynch" that allows one to easily copy directories and files across the ssh proxy host, without having to do two explicit copies: the '-e' option allows for a replacement "rsh" command. We use this option to specify an "ssh" tunnel command, with the '-A' option that causes authentication agent requests to be forwarded back to the local host. If you have ssh set up correctly, the above command can be done without any passwords being entered.

Open a file in a GTK+ dialog window
I use zenity because it's a rewrite of gdialog and also replaces gmessage and has more useful options. Using --text-info allows you to select and copy the text to your clipboard. To see a file in a list dialog: cat /etc/passwd | zenity --width 800 --height 600 --list --column Entries If you don't have zenity, you'll have to download it via apt-get install zenity, etc.

list files recursively by size

Get AWS temporary credentials ready to export based on a MFA virtual appliance
You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials

Auto-log commands
A quick alias I use right before logging into a server so that I have a log of the transactions as well as the ability to re-connect from another computer. Useful for when your boss says "what commands did you run again on that server?" and you had already closed the terminal ;) I wrapped it in a script now, with more features, but this is the heart of it. Never leave home without it.

Sync the existing directory structure to destination, without transferring any files
