Let's make screen and ssh-agent friends

determine if a shared library is compiled as 32bit or 64bit

file displays a files type the -L flag means follow sym-links (as libraries are often sym-linked to another this behavior is likely preferred) more complex behavior (*two* grep commands!) could be used to determine if the file is or is not a shared library.

determine if a shared library is compiled as 32bit or 64bit

Determines the flavor of a shared library by looking at the addresses of its exposed functions and seeing if they are 16 bytes or 8 bytes long. The command is written so the library you are querying is passed to a variable up font -- it would be simple to convert this to a bash function or script using this format. Show Sample Output

```
/lib32/libgcc_s.so.1 is a 32 bit library

sort selected lines in a text file to the beginning or end of the file.

This function is used to sort selected lines of a text file to the end of that file. Especially useful in cases where human intervention is necessary to sort out parts of a file. Let's say that you have a text file which contains the words rough slimy red fluff dough For whatever reason, you want to sort all words rhyming with 'tough' to the bottom of the file, and all words denoting colors to the top, while keeping the order of the rest of the file intact. '$EDITOR' will open, showing all of the lines in the given file, numbered with '0' padding. Adding a '~' to the beginning of the line will cause the line to sort to the end of the file, adding '!' will cause it to sort to the beginning. Show Sample Output
This is sample output - yours may be different.
```
$ 2end /tmp/2end.txt
~000001 rough
000002  slimy
!000003 red
~000004 fluff
000005  dough
$ cat /tmp/2end.txt 
red

dough
rough

print all network interfaces' names and IPv4 addresses

ifconfig can't properly display interface's name longer 9 symbols,also it can't show IPs added thru ip command, so 'ip' should be used instead. This alias properly shows long names, bond interfaces and all interface aliases. loopback interface is ignored, since its IP is obvious Show Sample Output

Top ten (or whatever) memory utilizing processes (with children aggregate)

This command loops over all of the processes in a system and creates an associative array in awk with the process name as the key and the sum of the RSS as the value. The associative array has the effect of summing a parent process and all of it's children. It then prints the top ten processes sorted by size. Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Is it a terminal?

Oddly, the isatty(3) glibc C call doesn't have a direct analogue as a command 'isatty(1)'. All is not lost as you can use test(1). For example, your script might be run from a tty or from a GUI menu item but it needs to get user-input or give feedback. Now your script can test STDIN with 'isatty 0' or STDOUT with 'isatty 1' and use xmessage(1) if the tty is not available. The other way to test for this is with 'tty -s' - but that's only for STDIN.

Test load balancers

With the "--resolve" switch, you can avoid doing DNS lookups or edit the /etc/hosts file, by providing the IP address for a domain directly. Useful if you have many servers with different IP addresses behind a load balancer. Of course, you would loop it: $ for IP in 10.11.0.{1..10}; do curl --resolve subdomain.example.com:80:$IP subdomain.example.com -I -s; done

generate random mac address

Reclaim standard in from the tty for a script that is in a pipeline

This will grab the controlling tty regardless of what STDOUT and STDERR are doing.

Remove invalid key from the known_hosts file for the IP address of a host

Quick shortcut if you know the hostname and want to save yourself one step for looking up the IP address separately.

shell bash iterate number range with for loop

Bash's arithmetic evaluation.

list block devices

Shows all block devices in a tree with descruptions of what they are.

drop first column of output by piping to this

Backup with versioning

Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

Display the human-readable sizes of all files and folders in the current directory with 3 decimal places

To sort the list by file/directory size, insert `sort -n |` before `awk`.
