[SOLVED] bash script generates error "No such file or directory".

nelson1387 · 10-20-2021, 01:47 PM

Hello:

I have a script that renames files in the current directory.

#!/bin/bash

mv file01.jpg newfile01.jpg
mv file02.jpg newfile02.jpg
.
.
.
mv filenn.jpg newfilenn.jpg

When I run the mv command from terminal, the command works. When I run a script, it comes back with No such file or directory. When I execute from Finder the error is No such file or directory for each command. Have I missed a step in creating the script?

macOS?

How do you execute the script?

Code:

bash your_script_name

Do you really have a file named filenn.jpg or does nn stand for a number? Then show us the real script.

BTW, does you system have the command rename?

Welcome. Which distro?

Double check the working directory which the script is using, it sounds like it may be different. Use cd and pwd for that.

If you are doing a bulk rename, you might see if the prename version of rename is on your system.

Code:

prename -n 's/^file([0-9]{2}).jpg/newfile$1.jpg/' file*.jpg
man prename

It is the perl variant of that utility and can take any perl expression, not just regular expressions. So you can count or add or whatever as part of the renaming.

make sure you have execute perms on the script

Code:

chmod +x /path/to/your/script

Try running it again from the command line and see what happens.

just a note: the current directory is local, all the apps/programs have their own current directories. Therefore you may need to put a cd <required dir> in that script before those mv lines.
