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 {{[-n|--dry-run]}} --rename --literal --from '{{find_string}}' --to '{{replacement_string}}' {{*.png}}

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

repren --rename {{[-n|--dry-run]}} --from '{{regex}}' --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 {{[-p|--patterns]}} {{path/to/patfile.ext}} --full {{*.txt}}

• Do a case-insensitive rename:

repren --rename {{[-i|--insensitive]}} {{[-p|--patterns]}} {{path/to/patfile.ext}} *
