ls -qahlSr # list all files in size order - largest last

I find it useful, when cleaning up deleting unwanted files to make more space, to list in size order so I can delete the largest first. Note that using "q" shows files with non-printing characters in name. In this sample output (above), I found two copies of the same iso file both of which are immediate "delete candidates" for me.

exa

nothing fancy `ls` alternative `exa`, with most info printed and passed through less with the `-R` (raw) option, to preserve colour output https://github.com/ogham/exa You can add or remove `-@` to print extended attributes for files that have them. Show Sample Output

What's this?

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

list files recursively by size

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Show Mac OS X version information

Have netcat listening on your ports and use telnet to test connection

This will start a netcat process listening on port 666. If you are able connect to your your server, netcat will receive the data being sent and spit it out to the screen (it may look like random garbage, so you might want to redirect it to a file).

Pretty man pages under X

You're a developer - but it doesn't mean you have to slum it! Why not spice up your man page lookups by using a decent PDF viewer. I use 'xpdf' - maybe you prefer acroread, whatever, it's just as fast as plain dull ASCII on today's machines and you can still search for stuff - that's the main reason I use PDF and not PS.

netstat with group by ip adress

urldecoding

$ echo "http%3A%2F%2Fwww.google.com" | sed -e's/%$[0-9A-F][0-9A-F]$/\\\\\x\1/g' | xargs echo -e http://www.google.com $ Works under bash on linux. just alter the '-e' option to its corresponding equivalence in your system to execute escape characters correctly.

Revert an SVN file to previous revision

M - current revision, N - older revision

randomize hostname and mac address, force dhcp renew. (for anonymous networking)

this string of commands will release your dhcp address, change your mac address, generate a new random hostname and then get a new dhcp lease.
