How do I rename files in directory and subdirectory?
I found this program, but I need to go change files in subdirectory.
for file in *#me01
do
mv "$file" "${file/#me01/_me01}"
done
n#me01
to
n_me01
The following one-liner will likely work for you:
find . -type f -name '*#me01' -execdir rename '#me01' '_me01' {} \;
The following form is likely more correct as it will change only the last # to _ if there are multiple occurrences of #me01 in the file:
for f0 in $(find . -type f -name '*#me01')
do
f1=$(printf '%s' "$f0" | sed 's/#me01$/_me01/')
mv "$f0" "$f1"
done
This latter form is also more flexible and can be built upon more easily as the regex language in sed is much more powerful than rename expressions.
If rename of directories is also required the following can easily be added...
Either:
find . -type d -name '*#me01' -execdir rename '#me01' '_me01' {} \;
Or:
for d0 in $(find . -type d -name '*#me01')
do
d1=$(printf '%s' "$d0" | sed 's/#me01$/_me01/')
mv "$d0" "$d1"
done
Using bash:
shopt -s globstar
for name in **/*#me01; do
mv "$name" "${name%#me01}_me01"
done
This enables the globstar shell option in bash which makes ** match across path separators in pathnames.
It also uses a standard parameter substitution to delete the #me01 portion at the very end of the found pathname and replace it with _me01.

Is there any way to get the basename in the command find?
What I don't need:
find /dir1 -type f -printf "%f\n"
find /dir1 -type f -exec basename {} \;
Why you may ask? Because I need to continue using the found file. I basically want something like this:
find . -type f -exec find /home -type l -name "*{}*" \;
And it uses ./file1, not file1 as the agrument for -name.
Thanks for your help :)
If you've got Bash version 4.3 or later, try this Shellcheck-clean pure Bash code:
#! /bin/bash -p
shopt -s dotglob globstar nullglob
for path in ./**; do
[[ -L $path ]] && continue
[[ -f $path ]] || continue
base=${path##*/}
for path2 in /home/**/*"$base"*; do
[[ -L $path2 ]] && printf '%s\n' "$path2"
done
done
shopt -s ... enables some Bash settings that are required by the code:
dotglob enables globs to match files and directories that begin with .. find shows such files by default.
globstar enables the use of ** to match paths recursively through directory trees. globstar was introduced in Bash 4.0, but it was dangerous to use before Bash 4.3 (2014) because it followed symlinks when looking for matches.
nullglob makes globs expand to nothing when nothing matches (otherwise they expand to the glob pattern itself, which is almost never useful in programs).
See Removing part of a string (BashFAQ/100 (How do I do string manipulation in bash?)) for an explanation of ${path##*/}. That always works, even in some rare cases where $(basename "$path") doesn't.
See the accepted, and excellent, answer to Why is printf better than echo? for an explanation of why I used printf instead of echo to output the found paths.
This solution works correctly if you've got files that contain pattern characters (?, *, [, ], \) in their names.
Spawn a shell and make the second call to find from there
find /dir1 -type f -exec sh -c '
for p; do
find /dir2 -type l -name "*${p##*/}*"
done' sh {} +
If your files may contain special characters in their names (like [, ?, etc.), you may want to escape them like this to avoid false positives
find /dir1 -type f -exec sh -c '
for p; do
esc=$(printf "%sx\n" "${p##*/}" | sed "s/[?*[\]/\\\&/g")
esc=${esc%x}
find /dir2 -type l -name "*$esc*"
done' sh {} +
You'll have to forward it to another evaluator. There is no way to do that in find.
find . -type f -printf '%f\0' |
xargs -r0I{} find /home -type l -name '*{}*'
This answers your question about trying to merge the functionality of %f and -exec find and is based on your example but your example injects raw filenames as -name patterns so avoid that and look at other solutions instead.
Simply spawn a bash shell:
find /dir1 -type f -exec bash -c '
base=$(basename "$1")
echo "$base"
do_something_else "$base"
' bash {} \;
$1 in the bash part is each file filtered by find.
I have a large directory of folders, each of which has only one file:
directory/folder1/208hasdfasdf.jpg
directory/folder2/f230fsdf.gif
directory/folder3/23fsdbfasf.jpg
I'd like to rename this to:
directory2/folder1/folder1.jpg
directory2/folder2/folder2.gif
directory3/folder3/folder3.jpg
How can I do that?
For the path and filenames shown, you can use a loop and combination of find and sed to make the substitutions, e.g.
for f in $(find directory -type f -wholename "*folder*"); do
mv "$f" $(sed -E 's|^([^/]+)/([^/]+)/([^.]+)[.](.*)$|\1/\2/\2.\4|' <<< "$f")
done
Where sed -E 's|^([^/]+)/([^/]+)/([^.]+)[.](.*)$|\1/\2/\2.\4| uses the alternative delimiter '|' instead of '/' to ease dealing with pathnames, and then separates and captures the "directory" with ^([^/]+) and then the "folderX" with ([^/]+), followed by the filename without the extension ([^.]+) and lastly the extension (.*)$ making each component available through the numbered backreferences \1, \2, \3, and \4, respectively.
Then to form the new filename, you just duplicate the \2 foldername in place of the \3 filename, for a new filename of \1/\2/\2.\4
Example Use/Output
$ find tmp-david -type f -wholename "*folder*"
tmp-david/folder3/23fsdbfasf.jpg
tmp-david/folder2/f230fsdf.gif
tmp-david/folder1/208hasdfasdf.jpg
And the replacement of the filenames with
$ for f in $(find tmp-david -type f -wholename "*folder*"); do
> mv "$f" $(sed -E 's|^([^/]+)/([^/]+)/([^.]+)[.](.*)$|\1/\2/\2.\4|' <<< "$f")
> done
Resulting in:
$ find tmp-david -type f -wholename "*folder*"
tmp-david/folder3/folder3.jpg
tmp-david/folder2/folder2.gif
tmp-david/folder1/folder1.jpg
You could try something like this, assuming you're using bash:
find directory/ \( -name '*.gif' -o -name '*.jpg' \) -print |
while read old; do
parent=${old%/*}
base=${parent##*/}
ext=${old##*.}
mv $old $parent/$base.$ext
done
If you're dealing with filenames that contain whitespace you're going
to need to massage this a bit.
Before running this script:
$ find directory -type f -print
directory/folder2/f230fsdf.gif
directory/folder1/208hasdfasdf.jpg
directory/folder3/23fsdbfasf.jpg
After running this script:
$ find directory -type f -print
directory/folder2/folder2.gif
directory/folder1/folder1.jpg
directory/folder3/folder3.jpg
I want to rename a file present in several subdirectories using bash script.
my files are in folders:
./FolderA/ABCD/ABCD_Something.ctl
./FolderA/EFGH/EFGH_Something.ctl
./FolderA/WXYZ/WXYZ_Something.ctl
I want to rename all of the .ctl file with the same name (name.ctl).
I tried several command using mv or rename but didnt work.
Working from FolderA:
find . -name '*.ctl' -exec rename *.ctl name.ctl '{}' \;
or
for f in ./*/*.ctl; do mv "$f" "${f/*.ctl/name .ctl}"; done
or
for f in $(find . -type f -name '*.ctl'); do mv $f $(echo "$f" | sed 's/*.ctl/name.ctl/'); done
Can you help me using bash?
thanks
You can do this with one line with:
find . -name *.ctl -exec sh -c 'mv "$1" `dirname "$1"`/name.ctl' x {} \;
The x just allows the filename to be positional character 1 rather than 0 which (in my opinion) wrong to use as a parameter.
Try this:
find . -name '*.ctl' | while read f; do
dn=$(dirname "${f}")
# remove the echo after you sanity check the output
echo mv "${f}" "${dn}/name.ctl"
done
find should get all the files you want, dirname will get just the directory name, and mv will perform the rename. You can remove the quotes if you're sure that you'll never have spaces in the names.
I would like to replace :2f with a - in all file/dir names and for some reason the one-liner below is not working, is there any simpler way to achieve this?
Directory name example:
AN :2f EXAMPLE
Command:
for i in $(find /tmp/ \( -iname ".*" -prune -o -iname "*:*" -print \)); do { mv $i $(echo $i | sed 's/\:2f/\-/pg'); }; done
You don't have to parse the output of find:
find . -depth -name '*:2f*' -execdir bash -c 'echo mv "$0" "${0//:2f/-}"' {} \;
We're using -execdir so that the command is executed from within the directory containing the found file. We're also using -depth so that the content of a directory is considered before the directory itself. All this to avoid problems if the :2f string appears in a directory name.
As is, this command is harmless and won't perform any renaming; it'll only show on the terminal what's going to be performed. Remove echo if you're happy with what you see.
This assumes you want to perform the renaming for all files and folders (recursively) in current directory.
-execdir might not be available for your version of find, though.
If your find doesn't support -execdir, you can get along without as so:
find . -depth -name '*:2f*' -exec bash -c 'dn=${0%/*} bn=${0##*/}; echo mv "$dn/$bn" "$dn/${bn//:2f/-}"' {} \;
Here, the trick is to separate the directory part from the filename part—that's what we store in dn (dirname) and bn (basename)—and then only change the :2f in the filename.
Since you have filenames containing space, for will split these up into separate arguments when iterating. Pipe to a while loop instead:
find /tmp/ \( -iname ".*" -prune -o -iname "*:*" -print \) | while read -r i; do
mv "$i" "$(echo "$i" | sed 's/\:2f/\-/pg')"
Also quote all the variables and command substitutions.
This will work as long as you don't have any filenames containing newline.
I have a lot of files whose names end with '_100.jpg'. They spread in nested folder / sub-folders. Now I want a trick to recursively copy and rename all of them to have a suffix of '_crop.jpg'. Unfortunately I'm not familiar with bash scripting so don't know the exact way to do this thing. I googled and tried the 'find' command with the '-exec' para but with no luck.
Plz help me. Thanks.
find bar -iname "*_100.jpg" -printf 'mv %p %p\n' \
| sed 's/_100\.jpg$/_crop\.jpg/' \
| while read l; do eval $l; done
if you have bash 4
shopt -s globstar
for file in **/*_100.jpg; do
echo mv "$file" "${file/_100.jpg/_crop.jpg}"
one
or using find
find . -type f -iname "*_100.jpg" | while read -r FILE
do
echo mv "${FILE}" "${FILE/_100.jpg/_crop.jpg}"
done
This uses a Perl script that you may have already on your system. It's sometimes called prename instead of rename:
find /dir/to/start -type f -iname "*_100.jpg" -exec rename 's/_100/_crop' {} \;
You can make the regexes more robust if you need to protect filenames that have "_100" repeated or in parts of the name you don't want changed.
