commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. 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.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

A more simple way to join lines with paste command than sed.

pwd | xclip

Functions: pwd

Copy the current path. Use -selection clipboard to copy the string to clipboard.

c="cp -a";e="~";echo -e "\npaste\n";i=0;k="1"; while [[ "$k" != "" ]]; do read -a k;r[i]=$k;((i++));done;i=0;while :;do t=${r[i]};[ "$t" == "" ] && break; g=$(echo $c ${r[i]} $e);echo -e $g "\ny/n?";read y;[ "$y" != "n" ] && eval $g;((i++));done

command [options] [paste your variable here] parameter

command [options] [paste entire column of variables here] parameter


(hard-code command "c" and parameter "e" according to your wishes: in example shown command = "cp -a" and parameter = "~")


- Quick exchange only variable part of a long command line

- Make variable part to be an entire column of data (i.e. file list)

- Full control while processing every single item


Paste column of data from anywhere. I.e. utilize the Block Select Mode to drag, select and copy columns (In KDE Konsole with Ctrl+Alt pressed, or only Ctrl pressed in GNOME Terminal respectively).


You can paste only one single variable in a row. If there are more space separated variables in a row only first one will be processed, but you can arrange your variables in a column instead. To transpose rows to columns or vice versa look at Linux manual pages for 'cut' and 'paste'.


- add edit mode to vary command "c" and parameter "e" on the fly

- add one edit mode more to handle every list item different

- add y/n/a (=All) instead of only y(=default)/n to allowed answers


The code is not optimized, only the basic idea is presented here. It's up to you to shorten code or extend the functionality.

Calculate pi from the infinite series 4/1 - 4/3 + 4/5 - 4/7 + ...

This expansion was formulated by Gottfried Leibniz: http://en.wikipedia.org/wiki/Leibniz_formula_for_pi

I helped rubenmoran create the sum of a sequence of numbers and he replied with a command for the sequence: 1 + 2 -3 + 4 ...

This set me thinking. Transcendental numbers!

seq provides the odd numbers 1, 3, 5

sed turns them into 4/1 4/3 4/5

paste inserts - and +

bc -l does the calculation

Note: 100 million iterations takes quite a while. 1 billion and I run out of memory.

paste --serial file1 file2 file3
paste file1 file2 fileN > merged

Tags: merge paste join

Merge files, joining line by line horizontally.

Very useful when you have a lot of files where each line represents an info about an event and you want to join them into a single file where each line has all the info about the same event

See the example for a better understanding

(echo "" | xsel -o) ; (programa | wgetpaste -s dpaste | awk '{print $7}' | xsel -ai)

echo "vertical text" | fold -1
echo "vertical text" | grep -o '.'

User: dennisw
Functions: echo grep

Define a function

vert () { echo $1 | grep -o '.'; }

Use it to print some column headers

paste <(vert several) <(vert parallel) <(vert vertical) <(vert "lines of") <(vert "text can") <(vert "be used") <(vert "for labels") <(vert "for columns") <(vert "of numbers")

In the above example all files have 4 lines. In "file1" consecutive lines are: "num, 1, 2, 3", in "file2": "name, Jack, Jim, Frank" and in "file3": "scores, 1300, 1100, 980". This one liner can save considerate ammount of time when you're trying to process serious portions of data. "-d" option allows one to set series of characters to be used as separators between data originating from given files.
