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

since awk was already there one can use it instead of the 2 greps. might not be faster, but fast enough

tail -n +<N> <file> | head -n 1

Tail is much faster than sed, awk because it doesn't check for regular expressions.

cat ~/.ssh/id_rsa.pub | ssh <REMOTE> "(cat > tmp.pubkey ; mkdir -p .ssh ; touch .ssh/authorized_keys ; sed -i.bak -e '/$(awk '{print $NF}' ~/.ssh/id_rsa.pub)/d' .ssh/authorized_keys; cat tmp.pubkey >> .ssh/authorized_keys; rm tmp.pubkey)"

This one is a bit more robust -- the remote machine may not have an .ssh directory, and it may not have an authorized_keys file, but if it does already, and you want to replace your ssh public key for some reason, this will work in that case as well, without duplicating the entry.

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

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.

echo $(grep "^[^']\{3,5\}$" /usr/share/dict/words|shuf -n4)

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 .

awk 'BEGIN {srand} /^[a-z]{4,8}$/ {w[i++]=$0} END {while (j++<4) print w[int(rand*i)]}' /usr/share/dict/words

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.

awk -F\" '/^DocumentRoot/{print $2}' $(httpd -V | awk -F\" '/\.conf/{print $2}')
TIME=$( { time redis-cli PING; } 2>&1 ) ; echo $TIME | awk '{print $3}' | sed 's/0m//; s/\.//; s/s//; s/^0.[^[1-9]*//g;'

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

curl -s http://funnyjunk.com | gunzip

instead of

curl -s --compressed http://funnyjunk.com
