Commands using sort

Prevents the need for the grep & awk statements. Sort is optional if you don't care about the output order. The network range can also be specified as in the original post.

-A Display targets by address rather than DNS name. (Probably unnecessary...)

-a Show systems that are alive.

S fping -r1 -ag 192.168.nnn.0/24 2>/dev/null

Without sorting...

Seeing that _sort_ its been used, why not just _use_ it. ;)

sort command can sort month-wise (first three letters of each month).

See the sample output for clarification.

Sorting Stable ? NO. Take note if that matters to you.

Sample output suggests that sort performs unstable

sorting (see the relative order of two 'feb' entries).

svn log -v --> takes log of all

Filter1

--------

-r {from}{to} --> gives from and to revision

Filter2

--------

awk of line 'r'with numbers

Assign user=3rd column [ie; username]

Filter3

--------

if username = George

print details

Filter4

--------

Print lines starts with M/U/G/C/A/D

[* A Added * D Deleted * U Updated * G Merged * C Conflicted]

Filter5

--------

sort all files

Filter6

-------

Print only uniq file's name alone.

i'm using gawk, you may get varying mileage with other varieties. You might want to change the / after du to say, /home/ or /var or something, otherwise this command might take quite some time to complete. Sorry it's so obsfucated, I had to turn a script into a one-liner under 255 characters for commandlinefu. Note: the bar ratio is relative, so the highest ratio of the total disk, "anchors" the rest of the graph. EDIT: the math was slightly wrong, fixed it. Also, made it compliant with older versions of df.

creates associative array from apache logs, assumes "combined" log format or similar. replace awk column to suit needs. bandwidth per ip is also useful. have fun. I haven't found a more efficient way to do this as yet. sorry, FIXED TYPO: log file should obviously go after awk, which then pipes into sort.

This command simply outputs 10 files in human readable, that takes most space on your disk in current directory.

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.'

sorts the contents of a file without the need for a second file to take the sorted output.

as per eightmillion's comment.

Simply economical :)

This short snippet outputs the state of all containers available on your system. It is quite helpful to see which ones are running and which are stopped. Please notice that the "sort -u" is needed, otherwise running containers will be reported twice (see output of "lxc-ls" on its own for why)

Very useful for logs

This command shows a sorted list of the IP addresses from which there have been authentication errors via SSH (possible script kiddies trying to gain access to your server), it eliminates duplicates so it's easier to read, but you can remove the "uniq" command at the end, or even do a "uniq -c" to have a count of how many times each IP address shows in the log (the path to the log may vary from system to system)

making it "sound" more "natural" language like -- additionally sorting the longest words alphabetically:

this approach is using:

* to get at all lines of input

* post-"for" structure

* short-circuit-or in sort: if the lengths are the same, then sort alphabetically otherwise don't even evaluate the right hand side of the or

* -C sets all input and ouput channels to utf8

Takes a directory name as an argument (defaults to current directory if no arguments are given). Prints the newest file in the directory.

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) )

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.

This will get all links from a given URL, remove any duplicates, and output the result.
