In case sed and awk are not available you may use this to remove the last character from a string with "rev" and "cut".

like #9295, but awkish instead of perlish

This does the same thing that the command 'j_melis' submitted, but does it a lot quicker.

That command takes 43 seconds to complete on my system, while the command I submitted takes 6 seconds.

The improvement of this command over Strawp's original alternative is that you can specify the size of the words, in this particular case words between 3 and 5 character's long. It also excludes words that contain apostrophes, if you'd rather keep those words simply substitue [^'] for .

If you do not have shuf or an -R option in sort, you can fall back on awk. This provides maximum portability IMO. The command first collects words from the dictionary that match the criteria - in this case: lower case words with no punctuation that are 4 to 8 characters long. It then prints 4 random entries. I decided to print each word on a separate line to improve readability.

Outputs the real time it takes a Redis ping to run in thousands of a second without any proceeding 0's. Useful for logging or scripted action.

- all zips are in current folder

- FILENAME is file name that should be subsitute in all zips (new version of this file is in current folder)

If your version of curl does not support the --compressed option, use

instead of

Replace .py with .rb or .java to get the LOC of that particular filetype. An alternative is http://www.commandlinefu.com/commands/view/2812/make-a-statistic-about-the-lines-of-code

count connections, group by IP and port

to be executed from root. this works well on most commercial unix systems, have not tried on linux systems.

How to force a userid to log out of a Linux host, by killing all processes owned by the user, including login shells:

Why use grep and awk?

seq 20 | awk '{line=line sep $0; sep=" "} !(NR%5){print line; line=sep=""}'

Change the $domain variable to whichever domain you wish to query.

Works with the majority of whois info; for some that won't, you may have to compromise:

domain=google.com; for a in $(whois $domain | grep "Domain servers in listed order:" --after 3 | grep -v "Domain servers in listed order:"); do echo ">>> Nameservers for $domain from $a

Note that this doesn't work as well as the first one; if they have more than 3 nameservers, it won't hit them all.

As the summary states, this can be useful for making sure the whois nameservers for a domain match the nameserver records (NS records) from the nameservers themselves.
