Git reset added new files

1. No for-loop, but xargs. 2. Append "--" in git-reset HEAD command to deal with filenames contained leading hyphen/minus sign (-). 3. Add "--porcelain" option in git-status command for easy-to-parse format when scripting. 4. Add "--no-run-if-empty" option in xargs command to prevent you run it twice and accidentally reset all staged changes. 5. Use zero byte (NUL character) as line terminator instead of newline (\n) to make it more robust to deal with filename with whitespaces. pipe#1: git-status. pipe#2: Use "grep" to filter out "non-added" files. pipe#3: use "sed" to Trim out the leading three characters, reserve the filename. pipe#4: xargs + git-reset... p.s. The "HEAD" in git-reset can be omitted . And, maybe, the third part of this shell pipe (sed) has potential to be enhanced.

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.

Lists installed kernels

Get duration of an audio file in seconds.

This is an alternative to #9131. ffmpeg didn't work on my .au files, though it did on the .wav ones. Also useful if you don't have ffmpeg but do have sox. Handily, sox already reports in seconds (decimal).

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

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" }

Find the cover image for an album

This bash function uses albumart.org to find the cover for an album. It returns an amazon.com url to the image. Usage: albumart [artist] [album] These arguments can be reversed and if the album name is distinct enough, it may be possible to omit the artist. The command can be extended with wget to automatically download the matching image like this: $ albumart(){ local x y="$@";x=$(awk '/View larger image/{gsub(/^.*largeImagePopup\(.|., .*$/,"");print;exit}'

Mount a partition from dd disk image

Assuming we have a disk image, ie. created by $dd if=/dev/sda of=image.dd we can check the image's partition layout with $fdisk -ul image.dd then, we substitute "x" with starting sector of the partition we want to mount. This example assumes that the disk uses 512 B sectors

make a log of a terminal session

Creates a log of a session in a file called typescript. Or specify the file with: $script filename Exit the session with control-d.

Draw a Sierpinski triangle

OK, not the most useful but a good way to impress friends. Requires the "display" command from ImageMagick.

Count TCP States From Netstat

Counts TCP states from Netstat and displays in an ordered list.

convert unixtime to human-readable
