Filter (and map) in a shell pipe.
For the times you need to filter (or map) in a shell pipe.
Filtering (default): - reads input lines - runs command for each line - prints line if command was successful
Mapping (with --map):
- reads input lines
- runs command for each line
- if command was successful, output its stdout instead of the line
Only list files that contain cats:
bash
ls | fpipe grep -qi cats {}
Only keep files that do not contain cats:
bash
ls | fpipe -n grep -qi cats {} # short for --negate
Search for files that contain a list of patterns in the name:
bash
cat patterns | fpipe -m fd {} # short for --map
If {} is not present in the command arguments, the line is passed to the subprocess via stdin.
If {} is given, it gets replaced by each line in turn before execution.
bash
cargo install fpipe
``` fpipe 0.1.0
Filter (and map) in a shell pipe '{}' arguments to the command are replaced with input line before execution
USAGE: fpipe [FLAGS] [cmd-and-args]...
FLAGS: -h, --help Prints help information -m, --map perform mapping (only command output is emitted, only if successful) -n, --negate negate the command exit status -q, --quiet suppress stdout of subcommand (stderr is still propagated) -V, --version Prints version information
