Recursively change file extensions in Bash
bash, linux, regex, sh, shell
Solution
Use:
find . -name "*.t1" -exec bash -c 'mv "$1" "${1%.t1}".t2' - '{}' +
If you have `rename` available then use one of these:
find . -name '*.t1' -exec rename .t1 .t2 {} +
find . -name "*.t1" -exec rename 's/\.t1$/.t2/' '{}' +
For a single file use the `+` delimiter and for renaming all files at once use the `;` delimiter. Example: For a single file
find . -name "*.t1" -exec bash -c 'mv "$1" "${1%.t1}".t2' - '{}' +
And for all files in the scope of the find command:
find . -name "*.t1" -exec bash -c 'mv "$1" "${1%.t1}".t2' - '{}' \;
Problem
I want to recursively iterate through a directory and change the extension of all files of a certain extension, say `.t1` to `.t2`. What is the bash command for doing this?
