repren

Multi-pattern string replacement and file renaming tool. More information: https://github.com/jlevy/repren.

• Do a dry-run renaming a directory of PNGs with a literal string replacement:

repren --dry-run --rename --literal --from 'find_string' --to 'replacement_string' *.png

• Do a dry-run renaming a directory of JPEGs with a regular expression:

repren --rename --dry-run --from 'regular_expression' --to 'replacement_string' *.jpg *.jpeg

• Do a find-and-replace on the contents of a directory of CSV files:

repren --from '([0-9]+) example_string' --to 'replacement_string \1' *.csv

• Do both a find-and-replace and a rename operation at the same time, using a pattern file:

repren --patterns path/to/patfile.ext --full *.txt

• Do a case-insensitive rename:

repren --rename --insensitive --patterns path/to/patfile.ext *
