  • If you've ever wanted to change a text files contents without having to create an intermediate file. This is it. Ex is a part of vim. The command as given will delete ALL lines containing "delete this line" from the file. More Examples: print '%s/'this is a line'/'that is not the same line'/g\nwq' | ex file.txt will substitute the first string with the second string. print '3a\n'Inserted Line'\n.\n\nwq' | ex file.txt will insert the given line after line 3. CAVEAT, Some distro's like the print command, others like echo with this command. Also note there are NO error messages on failure, at least that I've ever seen. Ex can also be quite fussy as to how it takes strings, parameters, etc... I use at&t's ksh syntax may very with other shells.

  • If you follow my previous posting regarding "vipw" then no explanation required.The same method goes behind this command also.It will open an tmp file in vi editor to give you the enlisting to edit the group file.And most importantly to attach a lock with it.Once you are done ,the lock is released and the changed reflected to the original file.So you can securely edit the group file over the network without the fear of being tampered .

  • Securely stream a file from a remote server (and save it locally). Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth. This is an extension of snipertyler's idea. Note: This command uses an encrypted connection, unlike the original. Show Sample Output
