Programming :: Can't Remove Temporary Files Using Bash Script?
Nov 9, 2010
However, the ffmpeg command generates a temporary file blahblah.mpg.tmp of about 1GB per hour of transcoded video.My issue is that I can't seem to delete these files automatically from any bash script.Now from the command line, I can cd to the directory and just rm -f *.tmp and they get deleted. However, from my script, that same command doesn't remove those files. I thought maybe the file was in use, so I put a sleep command in for like an hour before the delete happens, but it still fails. I also put rm -f /mnt/mythtv/*.tmp in a root cronjob and it still doesn't delete the files.
If I just rm *.tmp I do get a prompt about "Are you sure you want to delete this write protected file?". But the -f switch seems to work fine as a normal user from the command line and just delete them.Does anyone have an idea how to troubleshoot this problem? The particular filesystem that the tmp files get generated on is on it's own xfs partition mounted as /mnt/mythtv.
Where exactly are the temporary files stored, in /tmp or /var/tmp. How can i remove temporary files through command line? What is the difference between these two directories?
I want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ; [1] 5052 useratdebian:/home/user/folder# find: missing argument to `-exec' [1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?
I want to remove duplicate or multiple similar lines from multiple files. I.e. if I have four files file1.txt file2.txt file3.txt and file4.txt and would like to find and remove similar lines from all these files keeping only one line from these similar lines. I only that uniq can be used to remove similar lines from a sorted file.
Flash Player ActiveX is always copying movie from I-net before playing it. Is it possible to load and play flash movies directly from any source without usage of temporary files to protect the movie from any other LOCAL outside access?
i have a table in a text file. How can i remove from that table for example "SLS= " if the value is empty? Is it possible to do it in bash awk or sed? [URL]
I'm trying to search through some pdf files and I'm doing so by converting them to text files using pdftotext which is fine but I'm trying to get the number of occurrences in a paragraph of different words and it's adding a new line character at what it thinks is the right hand margin. I'm trying to remove all these singe new line characters but keep the doubles and I can't seem to work it out. i.e.
This is some text that has been broken. Another paragraph. becomes This is some text that has been broken. Another paragraph
I have a script that calls for a file description on a core file. I then pull the name of the process that caused the core file. unfortunately, the process name is pulled with a leading ' amd a tailing'. I would like to remove the leading char and the last char.
I am writing a bash script to run everyday and output results to a file. When the same results are produced i want to overwrite the line from the previous day. (Or remove and add). So if the script finds a variable in a line. i want it to output the results to that line . sed -i did not work for me; sed: couldn't open temporary file ./sedTvOCEg: Permission denied
I need to rename the resulted searched files from a loopI have the following code:
find . -name DOC* | while read i do find $i -type f -name '*.txt' done
basically, I am searching for all txt files inside any folder starting with DOC name.this code is working fine with me.I need to rename those .txt files to .txtOLDOS: Ubuntu 10.4Bash shell
I am an uploader to a various hosts, so this tiny script me a lot. I make a rar archive and split files with 100mb. I could get 3-4 or even 76 parts of rar files and it would take me some time to paste all these urls to remote upload function of filehosting sites. For example:
Code:
server:/home/cober/downloads/teevee# ls -al total 358784 drwxrwxrwx 2 root root 4096 Dec 8 19:38 .
I'm new here and still searching how this forum works, but can anybody tell me where i can find the temporary internet files? In windows it was easy, but ubuntu 11.04 is totaly diferent. I use it now for 5 days and i'm happy i changed to ubuntu.
I was preparing a script which will remove all my files from directory which are 24 hour old.I tried some thing like thisfind . ( -name 'log.*' -mtime +1 ) -exec rm {}; but it is throughing error like : missing argument to exec.
What I want to do is to create a script that will interpret the following string and save into variables part of its name
m02_+1+7_London_0000$01.cfg as ------X-Y--City--------- X=1 Y=7 City=London
[code]....
then I want to copy the files that go all the files with the same City and X and Y to the same subfolder City/MX.Y I will need some help start doing that. And I think the first would be to get part of the filenames strings into variables.
I am trying to find a nightly backup if it was successfully copied over, rename it and curl, but it's always passing the check even if the file is older than specified. From the command line it does as it should. Example is here;
Code: find /backup -type f -mmin +4440 -exec echo "found" {} ; - nothing returned (good). Then I change the time
I'm making a small script for searching and doing some operations with photos, but I'm kinda stuck on this little function:
Code:
function findallformat { prefix="" if [ $1 = -pre ] then
[code]....
That function should find for every file with a certain type; and you can specify a prefix using a "-pre" followed by the prefix that you want to search. The format should be "stackable", so you can use as many types that you want, without repeating the same function on the code.
Example: findallformat -pre IMG_ .JPG .CR2 #That should search files that start with "IMG_" and finishes with .JPG and .CR2. My problem it's that, when I try to use it on the script, it says "bash: syntax error near `token' unexpected `}'"
I'm trying to rename a lot of files getting rid of the space on the names. For that purpose I wrote this very simple bash script, but for some reason is not working.
Code: for i in "$(ls)" do j=$(echo "$i" | sed 's/ /_/g') mv "$i" "$j"
done But what I get in return for each line is just one long file name with all the file names concatenated. I've tried with echo -e "$i" as well with no results. This has to be something really simple that I'm missing but I just can't see it.
I am trying to write a simple script to list all the files in a directory. The script I wrote was as below where the pdb_files is a directory and all the files which I want to list are in that folder.
Code: files=`ls -F pdb_files/*THERMO*` for inFiles in $files do echo $inFiles
I hope you can help. I have a collection of spreadsheets with data that needs to be imported in to SQL. The data has been manually entered although there are portions where data has been copied and pasted from the web.
When converting these sheets to a CSV I get strange characters where it looks as though data has been copied and pasted. Is it possible to write a script (AWK?) to pull out these characters?
I guess the script will need to keep alpha characters, spaces, numerics and commas but nothing else. How easy is this to do?
Thanks y'all for the great script and explanation. This helped a lot in my own project. I thought I'd share the efforts.The project is this: I've got lots of duplicate JPGs from all the family members who've named the same photo with different names. Since md5sum generates a "fingerprint" based on the file contents, not the name, I want to use the md5sum of each jpg to uniquely name each photo and also remove exact duplicates.
It has the following flaws: 0) it doesn't handle certain non-alphanumerics 1) it keeps both photo-shopped and unaltered photos (different md5s) 2) it (currently) doesn't preserve descriptive filenames.
(For me, removal of duplicates is more important than keeping the filenames. I may change that to concatenate the md5 and the filename.)Please note that the commented "rename" command should be used to strip non-aphanumerics from the file names, and the script should be launched with the commented "find" command.
I have around 600 empty text files that I need to add the name of this file as part of the data, I meanfiles from "file1.txt to "file599.txt, all of them empty, and I need to get the name inside the file, so, when I open the file show the name as part the data "file1".these files were created on my web site, I am thinking in a small script in bash
How can I iterate over all the files in the current directory to check for certain permissions? This is what I have:
Code: #!/bin/bash for file in *.tar.gz do if [ -r "$file" ] then echo "$file is readable" else echo "$file is NOT readable" fi done
But this only checks that the current user has read permissions for each file. I want to check that the group "others" has read permissions for each file. How can I do this? Is there a built in function to check if a file has read permissions for the "others" group? Otherwise, I thought I might be able to use this: Code: $ stat --format=%a file 744 And parse the output "744" and make sure the 3rd number is between 4 and 7 (since the octals 4-7 have read permissions for others).
I'm building my first BASH programs and I have a hard time. I can't do a search in a folder and filter only script files without extension, the problem is to differentiate the script files from the others. I tried with ls I tried with find and i don't find a way to make it work.
