Check These Out

Display network pc "name" and "workgroup"
Checks for PC samba name and workgroup. Works fine for Windows hosts and Linux/UNIX PCs running Samba.

Recursive search and replace (with bash only)
Replaces a string matching a pattern in one or several files found recursively in a particular folder.

Two command output
Summarize established connections after netstat output. Using tee and /dev/stderr you can send one command output to terminal before executing wc so you can summarize at the bottom of the output.

execute your commands hiding secret bits from history records
$ wget --user=username --password="$password" http://example.org/ Instead of hiding commands entirely from history, I prefer to use "read" to put the password into a variable, and then use that variable in the commands instead of the password. Without the "-e" and "-s" it should work in any bourne-type shell, but the -s is what makes sure the password doesn't get echoed to the screen at all. (-e makes editing work a bit better)

Print all open regular files sorted by the number of file handles open to each.
This command run fine on my Ubuntu machine, but on Red Hat I had to change the awk command to `awk '{print $10}'`.

List the largest directories & subdirectoties in the current directory sorted from largest to smallest.

Find recursively, from current directory down, files and directories whose names contain single or multiple whitespaces and replace each such occurrence with a single underscore.
Note the g for global in the perl expression; without it, only the first occurrence in the name would be replaced.

Show a script or config file without comments or blank lines

Set all CPU cores' CPU frequency scaling governor to maximum performance

Adding Prefix to File name
