repren

TLDR

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] *
