Create a tar archive using 7z compression

Using 7z to create archives is OK, but when you use tar, you preserve all file-specific information such as ownership, perms, etc. If that's important to you, this is a better way to do it.
This is sample output - yours may be different.

tar cf - /path/to/data | 7z a -si archivename.tar.7z

List contents of tar archive within a compressed 7zip archive

Sometimes it is handy to be able to list contents of a tar file within a compressed archive, such as 7Zip in this instance, without having to extract the archive first. This is especially helpful when dealing with larger sized files.

Create Solid Archive (best compression) with 7z

Creates a solid archive with the highest possible compression (Ultra). Advantage of 7z is that it will use all the processor cores to create the archive. (Ok. at least version 9.04 does) Show Sample Output

Best option set for 7zip compression of database dumps or generic text files

These re the best option combination that works fine for compressing my database dumps. It's possible that there are another option or value that might improve the compression ratio, by these are the ones that worked, the syntax for 7zr it's a little messy...

Create a tar archive using xz compression

Compress files or a directory to xz format. XZ has superior and faster compression than bzip2 in most cases. XZ is superior to 7zip format because it can save file permissions and other metadata data.

Print a list of installed Perl modules

Works only if modules are installed "the right way"

List PHP-FPM pools by total CPU usage

Ping all hosts on 192.168.1.0/24

kill some process (same as others) but parsing to a variable

Kills a process matching program. I suggest using $ pgrep -fl program to avoid over-killings Nice the following: kills all bash process owned by guest $ pkill -9 -f bash -u guest

Grep auth log and print ip of attackers

Work for me on CentOS, grep and print ip addresses of ssh bruteforce attempts

View any archive

Part of the "atool" package.

Copy specific files recursively using the same tree organization.

This command has been used to overwrite corrupted "entries" files of a corrupted subversion working copy. Note the --files-from input format.

Recursively find top 20 largest files (> 1MB) sort human readable format

Search for files and list the 20 largest. $ find . -type f gives us a list of file, recursively, starting from here (.) $ -print0 | xargs -0 du -h separate the names of files with NULL characters, so we're not confused by spaces then xargs run the du command to find their size (in human-readable form -- 64M not 64123456) $ | sort -hr use sort to arrange the list in size order. sort -h knows that 1M is bigger than 9K $ | head -20 finally only select the top twenty out of the list

Browse shared folder when you're the only Linux user

Under Ubuntu smbclient is part of the samba package. With the version I use (3.0.28a) cd-ing into folders with spaces in the name is a drag. You have to put the folder name in quotes: smb: \Shared\> cd "Marketing and PR"

Normalize volume output in MPlayer

Works really well for playing DVDs, which have the volume turned way down for some reason. The `2' method is better IMHO because it will adjust to changing loud/soft parts. If you want to add it to your ~/.mplayer/config: # format: volnorm[=method:target] # method: # 1: use single sample (default) # 2: multiple samples # target: # default is 0.25 af-add=volnorm=2:0.75
