So in a bashscript i've the following very simple line , but how can i chain it further to move the file ?
find . -type f -ctime -$2 -name "mylog*.log" | xargs bzip2
This works fine but i'd also like to move the file to a new directory once I am done with the bzip2.
One standard trick is to use a new script that does whatever you need. Here, I assume that ${OTHER_DIRECTORY} is an environment variable that says where to put the compressed files, but there are plenty of other (better!) ways to get that information to the script (such as specifying the directory as the first argument — as the last argument is a bad idea).
#!/bin/bash
for file in "$#"
do
bzip2 "$file"
mv "$file.bz2" "${OTHER_DIRECTORY:-/tmp}"
done
You then run that script with find:
find . -type f ctime -$2 -name "mylog*.log" -exec tinyscript.sh {} +
This is pretty effective. If you only want one mv command, you can consider something along the lines of:
bzip2 "$#"
bz2=()
for file in "$#"; do bz2+=( "$file.bz2" ) done
mv "${bz3[#]}" "${OTHER_DIRECTORY:-/tmp}"
This code works even if the path names contain spaces and other untoward characters.
One option might be something like this:
find . -type f -ctime -$2 -name "mylog*.log" -exec bzip2 {} \; -exec mv {} /path/to/new_dir/ \;

I need to find and rename files with question mark in names.
Example: "style.css?ver=111" should become "style.css"
I use this command
find . -type f -name "*\?*" -exec rename 's/\?.*//' '{}' \;
In Debian all works fine, but in CentOS7 I get and error that "rename: not enough arguments
"
Any ideas why?
For a reliable option that should work in any POSIX-compliant system, you may use
find . -type f -name "*\?*" -exec sh -c 'mv -- "$1" "${1%%\?*}"' findshell {} \;
$1 is the name of each file found and ${1%%\?*} is a construct that strips the substring starting from the question mark.
That should be enough if you have a few matching files. If you need it, a more efficient alternative is
find . -type f -name "*\?*" -exec sh -c '
for file in "$#"; do
mv -- "$file" "${file%%\?*}"
done
' findshell {} +
Any idea why this is not working? I checked many links and I can't figure it out why I think the syntax is correct.
I want to find the file maplist.txt.old and then rename it to maplist.txt in the same folder. I got no errors.
find ~ -type f -name csgo/maplist.txt.old -execdir mv csgo/maplist.txt.old maplist.txt \;
Lots of ways to handle this. Since you are looking in ~/csgo you can go directly to the directory in the find. The -execdir option will run the command in the directory. So without changing your example much:
find ~/csgo -type f -name maplist.txt.old -execdir mv maplist.txt.old maplist.txt \;
To automate this a bit further, you may want to handle this with a bash for loop, for example:
for file in $( find ~/csgo -type f -name maplist.txt.old ) ; do
mv $file $( echo $file | sed -e 's/\.old//' )
done
I am trying to rename all files which contains 'Name' with dynamic name.
So this file 'NameSomething' should look like this 'SearchSomething'. But script below just removes 'Name' from file name.
name='search'
Name='Search'
find ../../$name-module -name 'Name*' -type f -exec bash -c 'mv "$1" "${1/Name/$Name}"' -- {} \;
You have to export Name, because otherwise the command find will not inherit the variable $Name into its environment. So:
name='search'
export Name='Search'
find ../../$name-module -name 'Name*' -type f -exec bash -c 'mv "$1" "${1/Name/$Name}"' -- {} \;
\You can escape quotes, no need for an export:
find ../../$name-module -name 'Name*' -type f -exec bash -c "mv \"\$1\" \"\${1/Name/$Name}\"" -- {} \;
You might use find to find a list of the files you want to rename and pipe that to another program to do the renaming.
For example, you could do:
find ../../$name-module -print0 -name 'Name*' -type f | \
xargs -0 rename "s/Name/$Name/"
No need for exporting (ugly + might affect other commands)
Rename might get run only once (if all the found files fit on one command line) (with -exec, you're running two programs -- bash and mv -- per each file. That might be inefficient.
(You could get further performance increase with this approach by using Gnu parallel instead of xargs, if you're on a multicore computer)
You could use the Perl-based rename command:
Name=Search
rename "s/^Name/$Name/" *
I'm trying to create a batch file in linux that will allow me to change extensions of files in multiple subdirectories. After much searching and experimenting i've found what seems to be a solution:
find /volume1/uploads -name "*.mkv" -exec rename .mkv .avi {} +
When running the script i get the following error:
find: -exec CMD must end by ';'
I've tried adding ; and \; (with or without +) but to no avail. What's wrong with the command and how can I fix it?
Edit: Running on a Synology NAS with DSM 4.2
you have to escape all characters that would be interpreted by bash. in your case these are the semicolon and the curly braces (you forgot to escape the latter in your code):
find /volume1/uploads -name "*.mkv" -exec rename .mkv .avi \{\} \;
the {} (in our case \{\}) is expanded to the filename, so the actual call would look like rename .mkv .avi /volume1/uploads/foo/bla.mkv (which is not the exact syntax the /usr/bin/rename needs, at least on my system).
instead it would be something like:
find /volume1/uploads -name "*.mkv" -exec rename 's/\.mkv$/.avi/' \{\} \;
UPDATE
if you don't want to (or cannot) use perl's rename script, you could use the following simple bash script and save it as /tmp/rename.sh
#!/bin/sh
INFILE=$1
OUTFILE="${INFILE%.mkv}.avi"
echo "moving ${INFILE} to ${OUTFILE}"
mv "${INFILE}" "${OUTFILE}"
make it executable (chmod u+x /tmp/rename.sh) and call:
find /volume1/uploads -name "*.mkv" -exec /tmp/rename.sh \{\} \;
UPDATE2
it turned out that this question is really not about bash but about busybox.
with a limited shell interpreter like busybox, the simplest solution is just to append the new file extension:
find /volume1/uploads -name "*.mkv" -exec mv \{\} \{\}.avi \;
Not sure how different find and rename commands are on your DSM 4.2 OS so try something like:
find /volume1/uploads -name "*.mkv" | while read filename;
do mv -v "${filename}" "$(echo "${filename}" | sed -e 's/\.mkv$/\.avi/')"
done
So basically, I have a folder with a bunch of subfolders all with over 100 files in them. I want to take all of the mp3 files (really generic extension since I'll have to do this with jpg, etc.) and move them to a new folder in the original directory. So basically the file structure looks like this:
/.../dir/recup1/file1.mp3
/.../dir/recup2/file2.mp3
... etc.
and I want it to look like this:
/.../dir/music/file1.mp3
/.../dir/music/file2.mp3
... etc.
I figured I would use a bash script that looked along these lines:
#!/bin/bash
STR=`find ./ -type f -name \*.mp3`
FILES=(echo $STR | tr ".mp3 " "\n")
for x in $FILES
do
echo "> [$x]"
done
I just have it echo for now, but eventually I would want to use mv to get it to the correct folder. Obviously this doesn't work though because tr sees each character as a delimiter, so if you guys have a better idea I'd appreciate it.
(FYI, I'm running netbook Ubuntu, so if there's a GUI way akin to Windows' search, I would not be against using it)
If the music folder exists then the following should work -
find /path/to/search -type f -iname "*.mp3" -exec mv {} path/to/music \;
A -exec command must be terminated with a ; (so you usually need to type \; or ';' to avoid interpretion by the shell) or a +. The difference is that with ;, the command is called once per file, with +, it is called just as few times as possible (usually once, but there is a maximum length for a command line, so it might be split up) with all filenames.
You can do it like this:
find /some/dir -type f -iname '*.mp3' -exec mv \{\} /where/to/move/ \;
The \{\} part will be replaced by the found file name/path. The \; part sets the end for the -exec part, it can't be left out.
If you want to print what was found, just add a -print flag like:
find /some/dir -type f -iname '*.mp3' -print -exec mv \{\} /where/to/move/ \;
