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.


If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

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.

Converts reserved characters in a URI to their percent encoded counterparts.

Alternate python version:

echo "$url" | python -c 'import sys,urllib;print urllib.quote(sys.stdin.read().strip())'
echo "$@" | sed 's/ /%20/g;s/!/%21/g;s/"/%22/g;s/#/%23/g;s/\$/%24/g;s/\&/%26/g;s/'\''/%27/g;s/(/%28/g;s/)/%29/g;s/:/%3A/g'
uri_escape(){ echo -E "$@" | sed 's/\\/\\\\/g;s/./&\n/g' | while read -r i; do echo $i | grep -q '[a-zA-Z0-9/.:?&=]' && echo -n "$i" || printf %%%x \'"$i" done }

This one uses hex conversion to do the converting and is in shell/sed only (should probably still use the python/perl version).

od -An -w999 -t xC <<< "$1" | sed 's/[ ]\?\(c[23]\) \(..\)/%\1%\2/g;s/ /\\\\\x/g' | xargs echo -ne

It only encodes non-Basic-ASCII chars, as they are the only ones not well readed by UTF-8 and ISO-8859-1 (latin-1).

It converts all

* C3 X (some latin symbols like ASCII-extended ones)

and * C2 X (some punctuation symbols like inverted exclamation)

...UTF-8 double byte symbols to escaped form that every parser understands to form the URLs. I didn't encode spaces and the rest of basic punctuation, but supposedly, space and others are coded as \x20, for example, in UTF-8, latin-1 and Windows-cp1252.... so its read perfectly.

Please feel free to correct, the application to which I designe that function works as expected with my assumption.

Note: I specify a w=999, I didn't find a flag to put unlimited value.

I just suppose very improbable surpass the de-facto 255 (* 3 byte max) = 765 bytes length of URL

Know a better way?

If you can do better, submit your command here.

What others think

Sure CLI-PHP is not available on many hosts, but your command is the shortest I've seen so far! Thanks!
