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?
View 4 RepliesI'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 want to count the number of files in each sub folder of a directory structure. At the moment I can do:
ls -1R /Folder | wc -l
Which lists the item count for all the folders as one. I can do:
ls -1R /Folder wc l
Which lists all the folders in the top level and all the items. Is there any way to get the list of folders and then item count for each folder?

I have a script that checks a folder for zip files than moves them to a different folder. I want to check every 5 maybe 10 seconds and since cron is setup to run at least a 1 minute increment I'm not sure how to do that time check as probably a loop within the script. One other thing is once the time check is in the script how would a cron job be setup to run this script? Once the script is running cron doesn't need to run it again, is there a feature to check if it's running and if it's not then run it?
find /export/xxxshare -name "*.zip" -exec mv {} /export/store ;
Can someone please help me on how can i create a script that will monitor file creation on a single folder and sending the newly created file on a separate folder? Only the new created file must be transffered or copied to the other folder. The old ones remains.I urgently need this for production deployment.
View 8 Replies View RelatedWay to test permissions on all files/folders into a folder recursive, then if those are not user:user then do :
Code:
chown user:user thatconcernedfile
The problem with that
Code:
chown user:user -R /folder
is that it is doing changes on file permissions whihch are already ok. If you wanna maintain a specific permission on a folder this is really not good this :
Code:
while [ 1 ] ; do

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 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.

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.

View 4 Replies View RelatedI 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 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'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.

View 3 Replies View Relateda 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.
