Compile all jpegs into 1 video by alphabetical order @ 50 fps

Most of the commands require the jpegs a certain format, not this, it just follows alphabetical order. The same order you follow if you do "ls -lisah" from top to bottom, top frame is first, bottom is last... This goes perfectly with a webcam timelapse... I have just the script for it: http://www.kossboss.com/linux---app-script---timelapse---capush Show Sample Output

This *does not change the video encoding*, so it's fast (almost purely I/O-bound) and results in a file of nearly the same size. However, OSX (and possibly other programs) will more easily play/seek the file when wrapped as MOV. For example, you can QuickLook the resulting file. This basically does the same as the commercial ClipWrap program, except using the free program ffmpeg. Show Sample Output

ffmpeg -i "input.mts" -vcodec copy -acodec pcm_s16le "output.mov"

replace audio track in a video file

The "map" may be different depending on the .wmv file. run `ffprobe` to see which is the video-track in the .wmv file usually this is "0.0". Stream #0.0: Video:... Stream #0.1: Audio: .. and "1.0" corresponds to the 2nd input file - your new audio. You may want to add "-acodec wmav2" and "-ar 128k" options for 128kbit/s Windows Media Audio 2 or whatever audio-codec/quality your want. `ffmpeg -codecs | grep "EA"` gives you a list of available codecs for Encoding Audio. Try using '-sameq' instead of '-vcodec copy' (re-encode the video with same quality rather than a bit-exact copy - this often solves muxing issues but will cause a small loss of either video quality or increased bandwidth). and also try a different output format eg. 'new_video.avi' or '..mov' instead of 'new_video.wmv'. you may need both, this should work: ffmpeg -i vid.wmv -i aud.wav -sameq -map 0.0 -map 1.0 output.avi

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.

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

Add 10 random unrated songs to xmms2 playlist

If you're like me and want to keep all your music rated, and you use xmms2, you might like this command. I takes 10 random songs from your xmms2 library that don't have any rating, and adds them to your current playlist. You can then rate them in another xmms2 client that supports rating (I like kuechenstation). I'm pretty sure there's a better way to do the grep ... | sed ... part, probably with awk, but I don't know awk, so I'd welcome any suggestions.

Change every instance of OLD to NEW in file FILE

Very quick way to change a word in a file. I use it all the time to change variable names in my PHP scripts (sed -i 's/$oldvar/$newvar/g' index.php)

Grep log between range of minutes

Returns logs between HH:M[Mx-My], for example, between 13:40 and 13:45.

Create a mirror of a local folder, on a remote server

Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Create a new file

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"

Backup a remote database to your local filesystem

I have this on a daily cronjob to backup the commandlinefu.com database from NearlyFreeSpeech.net (awesome hosts by the way) to my local drive. Note that (on my Ubuntu system at least) you need to escape the % signs on the crontab.
