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.

How can i search for example all .png files on an external disk and copy them to another directory?
Have tried to use the cp command. Have try it but don't work for me
?
Monterey 2.2.1
cp /Volumes/Data *.png /Volumes/Data/pictures_png
cp command won't work if you need to recursively copy from the sub directories. You need to use find.
Syntax:
find $SOURCE -type f -name '*.type' -exec cp '{}' $DESTINATION ';'
In your case,
find /Volumes/Data -type f -name '*.png' -exec cp '{}' /Volumes/Data/pictures_png ';'
Here is how it works:
-type f means copy only files not directories.
-name is to provide the filename to find. Here *.png for pattern matching
-exec executes the following line for each result the above find returns.
{} will be replaced with the results from find
; terminates -exec command
I am deleting the files in all the directories and subdirectories using the command below:
find . -type f -name "*.txt" -exec rm -f {} \;
But I want to know which are the files deleted along with their paths. How can I do this?
Simply add a -print argument to your find.
$ find . -type f -name "*.txt" -print -exec rm -f {} \;
As noted by #JonathanRoss below, you can achieve an equivalent result with the -v option to rm.
It's not the scope of your question, but more generally it gets more interesting if you want to delete directories recursively. Then:
a simple -exec rm -r argument keeps it silent
a -print -exec rm -r argument reports the toplevel directories you're operating on
a -exec rm -rv argument reports all you're removing
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"' {} \;
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.
