Is it possible to write a script to rename all files after the extension?
Example in the folder, there are :
hello.txt-123ahr
bye.txt-56athe
test.txt-98hg12
I want the output:
hello.txt
bye.txt
test.txt
If you just want to remove everything from the dash forwards, you can use Parameter expansion:
#!/bin/bash
for file in *.txt-* ; do
mv "$file" "${file%-*}"
done
Where ${file%-*}
means "remove from $file
everytning from the last dash". If you want to start from the first dash, use %%
.
Note that you might overwrite some files if their leading parts are equivalent, eg hello.txt-123abc
and hello.txt-456xyz
.
