Check These Out

wrap long lines of a text
wraps text lines at the specified width (90 here). -s option is to force to wrap on blank characters -b count bytes instead of columns

Search some text from all files inside a directory

sort the output of the 'du' command by largest first, using human readable output.
In this case I'm just grabbing the next level of subdirectories (and same level regular files) with the --max-depth=1 flag. leaving out that flag will just give you finer resolution. Note that you have to use the -h switch with both 'du' and with 'sort.'

Look for English words in /dev/urandom

List hostnames of all IPs

Pipe text from shell to windows cut and paste buffer using PuTTY and XMing.
Set up X forwarding in PuTTY, with X display location set to :0.0 Launch PuTTY ssh session. Launch Xming. Make sure that display is set to :0.0 (this is default). $ echo "I'm going to paste this into WINDERS XP" | xsel -i will insert the string into the windows cut and paste buffer.

scp with compression.
-C is for compression.

Transfer large files/directories with no overhead over the network
This invokes tar on the remote machine and pipes the resulting tarfile over the network using ssh and is saved on the local machine. This is useful for making a one-off backup of a directory tree with zero storage overhead on the source. Variations on this include using compression on the source by using 'tar cfvp' or compression at the destination via $ ssh user@host "cd dir; tar cfp - *" | gzip - > file.tar.gz

bash alias for sdiff: differ
this is just okey

strip non-constant number of directories from tar archive while decompressing
If you want to decompress the files from an archive to current directory by stripping all directory paths, use --transform option to strip path information. Unfortunately, --strip-components option is good if the target files have same and constant depth of folders. The idea was taken from http://www.unix.com/solaris/145941-how-extract-files-tar-file-without-creating-directories.html
