| [[Anchor(faq15)]] == How can I run a command on all files with the extension .gz? == Often a command already accepts several files as arguments, e.g. {{{ zcat *.gz }}} (One some systems, you would use {{{gzcat}}} instead of {{{zcat}}}. If neither is available, or if you don't care to play guessing games, just use {{{gzip -dc}}} instead.) If an explicit loop is desired, or if your command does not accept multiple filename arguments in one invocation, the {{{for}}} loop can be used: {{{ # Bourne for file in *.gz do echo "$file" # do something with "$file" done }}} To do it recursively, you should use a loop, plus the [:UsingFind:find] command: {{{ # Bash while read file; do echo "$file" # do something with "$file" done < <(find . -name '*.gz' -print) }}} For more hints in this direction, see [:BashFAQ/020:FAQ #20]. To see why the `find` command comes after the loop instead of before it, see [:BashFAQ/024:FAQ #24]. |
