Keep track of diff progress

When running a long `diff -r` over folders, this simulates a "verbose" mode where you can see where diff is in the tree. Replace $file with the first part of the path being compared.

Scan your LAN for unauthorized IPs

Show changed files, ignoring permission, date and whitespace changes

Only shows files with actual changes to text (excluding whitespace). Useful if you've messed up permissions or transferred in files from windows or something like that, so that you can get a list of changed files, and clean up the rest.

diff the same file in two directories.

This is useful when you're diffing two files of the same name in radically different directory trees. For example: Set path1='/some/long/convoluted/path/to/all/of/your/source/from/a/long/dead/machine' then path2='/local/version/of/same/file' then run the command. Much easier on the eyes when you're looking back across your command history, especially if you're doing the same diff over and over again.

Using commandoutput as a file descriptor

Description is moved to "Sample output" because the html sanitizer for commandlinefu breaks the examples.. Show Sample Output

diff rpm_output_from_other_computer <(rpm -qa|sort)

Displays user-defined ps output and pidstat output about the top CPU or MEMory users.

It grabs the PID's top resource users with $(ps -eo pid,pmem,pcpu| sort -k 3 -r|grep -v PID|head -10) The sort -k is sorting by the third field which would be CPU. Change this to 2 and it will sort accordingly. The rest of the command is just using diff to display the output of 2 commands side-by-side (-y flag) I chose some good ones for ps. pidstat comes with the sysstat package(sar, mpstat, iostat, pidstat) so if you don't have it, you should. I might should take off the timestamp... :| Show Sample Output

Diff two directories by finding and comparing the md5 checksums of their contents.

Compute the md5 checksums for the contents of two mirrored directories, then sort and diff the results. If everything matches, nothing is returned. Otherwise, any checksums which do not match, or which exist in one tree but not the other, are returned. As you might imagine, the output is useful only if no errors are found, because only the checksums, not filenames, are returned. I hope to address this, or that someone else will!

Unbelievable Shell Colors, Shading, Backgrounds, Effects for Non-X

I've been using linux for almost a decade and only recently discovered that most terminals like putty, xterm, xfree86, vt100, etc., support hundreds of shades of colors, backgrounds and text/terminal effects. This simply prints out a ton of them, the output is pretty amazing. If you use non-x terminals all the time like I do, it can really be helpful to know how to tweak colors and terminal capabilities. Like: $ echo $'\33[H\33[2J'

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Run bash on top of a vi session (saved or not saved), run multiple commands, instead of one at a time with :!(bashcommand), type exit and [enter] to get back to where you left off in vi.

Helps when I'm editing a script and want to double check some commands without having to exit out of vi multiple times or having to use another terminal session.
