I have many files without file extention. Now I want to add .txt to all files. I tried the following but it gives an error, mv: rename . to ..txt: Invalid argument.
How can I achieve this?
find . -iname "*.*" -exec bash -c 'mv "$0" "$0.txt"' {} \;
You're nearly there!
Just add -type f to only deal with files:
find . -type f -exec bash -c 'mv "$0" "$0.txt"' {} \;
If your mv handles the -n option, you might want to use it (that's the option to not overwrite existing files).
The error your having is because . is one of the first found by found, and your system complains (rightly) when you want to rename .! with the -type f you're sure this won't happen. Now if you wanted to act on everything inside your directory, you would, e.g., add -mindepth 1 at the beginning of the find command (as . is considered depth 0).
It is not very clear in your question, but what if you want to add the extension .txt to all files that don't have an extension? (we'll agree that to have an extension means to have a period in the name). In this case, you'll use the negation of -name '*.*' as follows:
find . -type f \! -name '*.*' -exec bash -c 'mv "$0" "$0.txt"' {} \;

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 {} +
I have a folder with tens of thousands of different file types. Id like to copy them all to a new folder (Copy1) but also rename them all to $RANDOM but keep the extension intact. I realize I can write a line specifying which extension to find and how to name it, but there is got to be a way to do it dynamically, because there are at least 100 file types and may be more in the future.
I have the following so far:
find ./ -name '*.*' -type f -exec bash -c 'cp "$1" "${1/\/123_//_$RANDOM}"' -- {} \;
but that puts the random number after the extension, and also it puts the all in the same folder. I cant figure out how to do the following 2 things:
1 - Keep all paths intact, but in a new root folder (Copy1)
2 - How to have name be $RANDOM.extension, instead of .extension.$RANDOM
PS - by $RANDOM i mean actual randomly generated number. I am interested in keeping folder structure, so we are dealing with a few hundred files at most per directory, but all directories/files need to be renamed to $RANDOM. Another way to look at what I need to do. Copy all contents or Folder1 with all subdirectories and files to Folder2 (where Fodler2 is a $RANDOM name), then rename all folders and files to random names but keep all extensions.
EDIT: Ok i figured out how to rename and keep extension. But I have a problem where its dumping all of the files into the root directory where script is run from. How do I keep them in their respective folders? Command Im using is:
find ./ -name '*.*' -type f -exec bash -c 'mv "$1" $RANDOM.${1##*.}' -- {} \;
Thanks!

Change your command to:
PATH=/bin:/usr/bin find . -name '*.*' -type f -execdir bash -c 'mv "$1" $RANDOM.${1##*.}' -- {} \;
Or alternatively using uuids instead of random numbers:
PATH=/bin:/usr/bin find . -name '*.*' -type f -execdir bash -c 'mv "$1" $(uuidgen).${1##*.}' -- {} \;
Here's what I came up with :
i=1
random="whatever"
find . -name "*.*" -type f | while read f
do
newbase=${f/*./$random$i.} //added counter to filename
cp $f /Path/Name/"$newbase"
((i++))
done
I had to add a counter to random (i), otherwise, if the extensions are similar, your files would overwrite themselves when copied.
In your new folder, your files should look like this :
whatever1.txt
whatever2.txt
etc etc
I hope this is what you were looking for.
Here is the command that worked for me.
find . -name '*.pdf' -type f -exec bash -c 'echo "{}" && cp "$1" ./$RANDOM.${1##*.}' -- {} \;
I want to rename folder/directory names recursively and found this solution on SO. However this command has no effect
find . -type f -exec rename 's/old/new/' '{}' \;
Is that a correct command?
find . -depth -name '*a_*' -execdir bash -c 'mv "$0" "${0//a_/b_}"' {} \;
The -depth switch is important so that the directory content is processed before the directory itself! otherwise you'll run into problems :).
100% safe regarding filenames with spaces or other funny symbols.
find /path/to/files -type f -not -name "M*'.jpg" -exec mv "{}" "{}".mxg \;
I fear I made two mistakes.
Files are stored in a directory structure. Goal is to keep the filenames and change the file extension from .jpg to .mxg. But only for files that have 'M' as the first character of there filename.
The above line has this result:
all files have .mxg added. So the .jpg isn't and all files are changed.
This should do it:
find /path/to/files -type f -name 'M*.jpg' -exec bash -c 'echo mv "$1" "${1/jpg/mxg}"' -- {} \;
A somewhat cleaner solution is if you have the rename command. However, there are different implementations out there, so read your man page first to check you have the same as mine. The version I have in Debian is Larry Wall's implementation in perl. You can recognize this by the example rename 's/\.bak$//' *.bak near the top, or the AUTHOR section near the bottom. With this implementation you can rename your files like this:
find /path/to/files -type f -name 'M*.jpg' -exec rename 's/jpg$/mxg/' {} \;
I basically have written a shell script in AIX that will delete some old log file and will compress some .
This is my script
#!/bin/sh
###
### Static variables
###
nmon_dir="/var/log/applog/nmon"
cd $nmon_dir
find $nmon_dir -xdev -type f -mtime +360 -name "*.nmon*" -exec rm {} \;
find $nmon_dir -xdev -type f -mtime +300 -name "*.nmon" -exec gzip {} \;
I could delete the files as i wanted but that I am not sure whether it compressed those file . Because i couldn't find .gz file both in root or /var/log/applog/nmon path .
Need Help!
Seems to me like your KSH might be taking the {} you pass to find as a compound command definition instead of as the filename placeholder. Try escaping it, I use it as \{\} and it never gives me problems.
