# Odd, sweet and still elegant.

In case you were wondering? This post is part of a series of which its master can be found here.

As I was wondering how ‘catenating’ avi files would/should work, I stumbled upon this short but elegant solution. *SWEET*

avimerge -o Name-of-your-choosing.avi -i $(ls)  In case the directory you work in contains several file types. avimerge -o Name-of-your-choosing.avi -i$(ls *.avi)


When the ordering of said files is odd at best!?

avimerge -o Name-of-your-choosing.avi -i $(ls *.avi | sort -n)  Only problem with this setup is, that if you want to ‘automate’ this process, avimerge keeps spewing errors at me?? However mencoder will work when used and needed as a ‘batch converter’ of sorts. 😉 mencoder -forceidx -oac copy -ovc copy$(ls) -o "$OUPUT"  In case the directory you work in contains several file types. mencoder -forceidx -oac copy -ovc copy$(ls *.avi) -o "$OUPUT"  When the ordering of said files is odd at best!? mencoder -forceidx -oac copy -ovc copy$(ls *.avi | sort -n) -o "$OUTPUT"  So here is an enhanced script which from now on also process(es) *.wmv and mp{e,eg,g,4} file(s) for you. Edited on: 10092011@11:15GMT) ## Invoke as: ./cat.files.sh$ARG
## Where $ARG is one of the following three. # avi, mpg or wmv ## Thus (in my case): # cat.files.sh avi ## Will catenate all the avi files it finds in the current working directory. ## However: # cat.files.sh avi wmv ## Will fail, because the script only accepts one argument passed to it. ## That's on purpose! ## But feel free to edit at will.

The only real difference in between command line usage and the use of a gui (to accomplish the same goal).
Is this: Speed!

Why? In a gui you turn options on and off with either the click (or a multitude of them) of the mouse or somewhat ‘faster’ =(reads as ‘more advanced’) by using shortcut keyboard options and has the benefit of being somewhat more ‘intuitive’.
The cli however can ‘act’ in a similar way (as it does for me now):

\$ somecommand -w -t -f /some/input/file /some/output/file


But requires the user to be able to think in a more ‘abstract’ manner.

Now you decide what’s best (for your situation?) 😉

I wanted to check up and allow you to know how much I treasured discovering this blog today. I’d personally consider it the honor to work at my company and be able to use the tips provided on your website and also take part in visitors’ comments like this. Should a position associated with guest publisher become available at your end, please let me know.

• While I’ve said a while ago on facebook: “Buying one’s way into heaven never did really work out for anyone”

I am going to add the following: “Sucking up one’s way into ****heaven does neither”
In other words you’ll have to do much better than this ‘to impress me’! 😆

As for the guest publishing. I already got me a person to put the comma’s and shit in the right places. Namely Me!

All kidding set aside though: I do welcome constructive criticism and I’d consider co-authoring material with people who actually know what they are talking about. That would be people who are me⁴ or something!?

Also one should consider my blog as the place where I so now and then “talk out loud”, nothing more… Me talking out loud may be of benefit to a few and a true pain in the ass to a few others. Honestly, I wouldn’t want to have it any other way.
