output the contents of a file removing any empty lines including lines which contain only spaces or tabs.

for loop with leading zero in bash 3

List only directory names

This command would be useful when it is desirable to list only the directories. Other options Hidden directory $ ls -d .*/ Other path $ ls -d /path/to/top/directory/.*/ Long format: $ ls -ld */

Find default gateway

Exclude svn directories with grep

exclude-dir option requires grep 2.5.3

convert unixtime to human-readable

Recording the desktop and an application audio source for webcast

Multi line grep using sed and specifying open/close tags

Working with log files that contains variable length messages wrapped between open and close tags it may be useful to filter the messages upon a keyword. This works fine with GNU sed version 4.2 or higher, so pay attention to some unix distros (solaris, hp-ux, etc.). Linux should be ok.

Create a mirror of a local folder, on a remote server

Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)
