Programming :: Batch Process Files In VI?
May 29, 2010
I'm completely new to scripting and I'm trying to figure out how to write a script that will get a list of all the files in a directorywn through any subdirectories.When I have the list I want to o each file in VI and change the fileformat. So far all I have been able to figure out is that VI can do the batch processing and that "ls -R" gets me the recursive file list. I'm still pretty clueless on how to do the batch process with the VI editor. I think I'm supposed to use the Ex mode but I don't know how to get the list of arguments from the filelist into the editor so they can be processed. If it matters the files were all written in a Windows editor and have gotten the MS carriage returns so I want to do a :set ff=unix command on all the files without having to go into each file manually, there are over 300 files that need updated.

I have some random files in a folder. I want to rename all of the files in a batch process. I have a text file that contains the Currentname of all the files in the folder, as well as a text file with all of the Newname of files in the folder. I want to replace Currentnames with Newnames.
For example, here are the names of the files in the folder:
1.mp4
2.mp4
3.mp4
I have a text file with the Currentname of all the files in the folder:
1.mp4
2.mp4
3.mp4
I have a text file with the proper Newname of the file:
a.mp4
b.mp4
c.mp4
I want to rename Currentname with Newname in the folder. So when I go to the folder the Newname of the files are:
a.mp4
b.mp4
c.mp4

I scanned hundreds of pages in gray scale and would like to batch process them to B&W. You can do this using the gimp GUI. what it does is get rid of all the gray shading from reflections off the paper when scanned. So you get crisp white backgrounds with black text and diagrams. I would like to simply do this to the entire group directory at one time as it would be quite a lot of effort to open them and do them one by one.

I have a lot of pdf files and I want to convert them to a lower quality for the web. I tried to use the following command (using ghostscript): Code: gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/default -dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf Is there a way to make a batch to do this for all pdf-s in a folder?

I don't know if it's possible but GIMP is able to receive command line arguments, so why not? Basically, I want to create a batch (action, macro or what it may be called) and then set up a cron job which will run every hour. So, it would be something like "If an image is in X folder, then resize, watermark & move it to Y folder".

I'm having trouble getting Dave's Batch Process program to install in GIMP. DBP - David's Batch Processor
I'm running 11.3 KDE 64bit.
The instructions say to put the dbp1.1.9 in the GIMP plugins folder. But it doesn't show up.

I recently installed JDK 6 runtime using apt-get install in terminal. I downloaded a .jar file and attempted to run it but I got an error telling me it has blocked the file for some reason.Another thing was, how can I run batch files? I know ubuntu doesn't come with something like MS DOS but is there anything similar that I can run batch files with?

As you already know there's a command in the "BATCH" language named pause which causes the program to get any random character and then continues the scripts (which is mostly used to keepscript running and preventing it to do its work and close the command prompt).Something like the "getch".Is there anything similar to this at bash?IMPORTANT NOTE: I don't want my script to stay opened, I want it to get a character (without hitting enter) and continue executing the rest of the script so please don't reply "Tick the keep the terminal opened option" or "Use read"

I have written the batch file which will go to the website, wait for input (download button/exit), move to the next algorithym and repeat. My problem is getting the batch file to click the stupid download button. Can I use wget, and can you show me how to use it or point me to a really good api?

I run a script which generated about 10k files in a directory. I just discovered that there is a bug in the script which causes some filenames to have a carriage return (presumably a '' character).
I want to run a sed command to remove the carriage return from the filenames.
Anyone knows which params to pass to sed to clean up the filenames in the manner described?
I am running on Linux (Ubuntu)
The character causing the filename to 'break up' accross multiple lines appear to be a CR (carriage return) instead of ' '. The filename is being diaplayed in thetitle of a text editor with %0D in the positions of where the file name breaks up. So I need to remove the CR chars from my filenames.

So I have a php script that is setup to stream flash video (.flv) and I absolutely love having it. The problem is that any files I want to stream have to be in .flv format for it to work properly as .avi and others obviously don't stream well. Up until now, I've used FFMpeg to change the format from .avi to .flv, however the process takes a lot of time if you have a lot of videos, added to that you have to do one file at a time definitely makes it a pain.Does anyone know of a bash script that can take all the files (i.e. avi, .wmv, .mkv, .mpeg4) in one folder and automatically convert it to .flv? Then possibly delete the old files? Low resolution is fine, so long as it at least viewable. Does anyone have a script or know of a program that can do this (I run Ubuntu 10.04). I think FFMpeg has the best chance of doing this, but I don't know the syntax to actually do so.
I've searched the internet, and while I have found a few scripts, they didn't work for me (still looking into two scripts I found.I am currently messing with them to see if I can get them to work).It would be immensely helpful if someone knew of a way to do this.I also forget to mention that I have used Winff, but I was looking more for a bash script to do this so that I can set a cron job to convert them every hour or so.

System - openSUSE 11.2 "Emerald" KDE (with gnome base)
Player - vlc
I'm hoping to find a batch of codecs for my newly installed openSUSE OS. I have a very troublesome collection of .mkv files that took several codec packs to make them work. For a brief explanation, I had tried haali and matroska both together and they still didn't work on certain mkvs. I ended up using CCCP, but that's win only as far as I can tell. It took the latest update of CCCP to work on all of my mkvs.

I have recently been tasked to extract the subtitles from a lot of mkv files. Hundreds of them, maybe even more than a thousand. To do this, I modified a script I found online:
#!/bin/bash
IFS="|"
if test -z $1; then
[Code].....
So in the above example the subtitle is actually in track number one and my script would be borked for that particular file. Is there a way to integrate mkvinfo into the script and parse it to see what track should be extracted? Like, read it line-by-line and change the value of some #TRACKNO variable everytime a string like "| + Track number:" appears, and stop when a string like "| + Track type: subtitles" appears? Maybe even skip doing anything if there aren't any subtitles.
PS: I actually prefer SRT subtitles to ***. If there was some command line tool I could use to convert the resulting *** file to SRT I would be much obliged.

I'm not asking for help here, just documenting something I just discovered. Yesterday I wanted to batch-convert a bunch of old wma files to ogg vorbis. Not wanting to go through intermediate wav files, I tried to use ffmpeg to do it in one go. I first tried using the following command (in a loop, which I won't print here).
Code:
ffmpeg -i $file -f ogg -acodec vorbis -ab 192k outputdir/$file "vorbis" turns out to be the built-in libavc implementation of the codec. In the process I discovered that the -ab value is always ignored. No matter what value you put, the output is always the default 64k (average, but of course it's vbr). You can however use the poorly-documented -aq option to set the audio quality used. The values don't correspond to the oggenc values though, being a number ranging from 10-100 (or more, I don't know what the maximum is). It's not exactly clear what number corresponds to what average bitrate, so you have to experiment. ~30 seems to give you an average-rate file, while anything above 60 is probably overkill.
Switching to the external libvorbis gave me more flexibility, although at a cost of much longer encoding times (note that ffmpeg must have been compiled with libvorbis support first).
Code:
ffmpeg -i $file -f ogg -acodec libvorbis -ab 192k outputdir/$file
ffmpeg -i $file -f ogg -acodec libvorbis -aq 6 outputdir/$file
I could use both -ab and -aq (with the numbers corresponding to the oggenc values), with no problems. ffmpeg does display some wrong values in it's output text, however. In addition, there's one more difference. The vorbis (libavc) codec provides an entry in the header of the ogg container reporting the average bitrate, but it doesn't appear to provide a similar bitrate header in the vorbis stream itself. Some programs may not report the bitrate value because of this.
libvorbis provides both headers, avoiding that problem. So to summarize, libvorbis appears to be a better codec choice than vorbis.

I have about 300 files that need renaming, because the file system does not display the French characters properly. The dodgy letter in question has been replaced by a "question mark in a black diamond" symbol.No way of renaming, other then using mv in the Konsole has worked. Is there any way, script or program out there, that will do a batch rename?

a movie is encoded with AC3 in 6 channel audio, what I get out is all of the sounds except for voices, which in 5.1 would be sent to the center channel. What I usually do is fire up avidemux and convert the audio to mp3 stereo, as converting to a 5.1 format usually ends up with a very odd sound (like running everything through an echo chamber). What I'd like to do is run a script to batch-convert these files from AC3 to MP3. The video format may vary, but they are usually XVID. I am comfortable at the command line, but I am not well-versed in audio/video tool terms. I don't need anything extravagant, I just want something that works. Heck, even if it is done one at a time, having a shell script that I can use to simply type:
tool.sh inputfile.avi outputfile.avi

I'm trying to clean up a few hundred thousand mp3 files and I'm dying to find a way to automate some of the mechanical tasks I keep doing. It seems like at least two of these tasks could be easily accomplished with something at the command line, but I don't have the chops/know-how to figure out how (and would really rather not trial and error with batch deleting files & folders...).
1) Delete all folders named "_MACOSX" (and all subfolders/files contained therein) -- Basically, I'd like to apply this command to a few hundred directories that may or may not contain a subfolder called "_MACOSX" that I'd really like to get rid of.
2) Delete all files named "*.m3u". -- Similar to the first, I want to automatically scan all directories and subdirectories in a given location for all instances of this file-type and delete them wherever they're found.
3) Move all files named *.txt", "*.doc", "*.pdf" to a specific location. -- Similar to the last, except instead of deleting, I'd like to just move them, so that if there is anything worth keeping, I can keep it.
