usage: pyxargs [-h] [-s] [-d base-directory] [-m mode] [-0] [--delim char]
[-a file] [-r regex] [-o] [-f] [-I replace-str]

[command-part [command-part ...]]
build and execute command lines from standard input or file paths, a mostly
complete implementation of xargs in python with some added pythonic features.
positional arguments:
command-part (default)
command-part[0] = base-command
command-part[1:N] = initial-argument(s)
(pyxargs -s)
command-part = "base-command [initial-argument(s)]"
optional arguments:
-h, --help show this help message and exit
-s interpret each command-part as a separate command to
be run sequentially
-d base-directory default: os.getcwd()
-m mode options are:
file = build commands from filenames and execute in
each subdirectory respectively (default)
path = build commands from file paths relative to
the base directory and execute in the base
directory
abspath = build commands from file paths relative to
root and execute in the base directory
dir = build commands from directory names instead
of filenames
stdin = build commands from standard input and
execute in the base directory
-0, --null input items are terminated by a null character instead
of by whitespace, automatically sets mode = stdin
--delim char input items are terminated by the specified delimiter
instead of whitespace a
662A
nd trailing whitespace is
removed, automatically sets mode = stdin
-a file read items from file instead of standard input to
build commands, automatically sets mode = stdin
-r regex only build commands from inputs matching regex
-o omit inputs matching regex instead
-f only match regex to filenames
-I replace-str replace occurrences of replace-str in the command(s)
with input, default: {}
--resub pattern repl replace-str
replace occurrences of replace-str in the command(s)
with re.sub(patten, repl, input)
--py executes command(s) as python code using exec(),
beware of side effects
--pyev evaluates command(s) as python expression(s) using
eval()
--imprt [library [library ...]]
runs exec("import " + library) on each library, beware
of side effects
--imprtstar [library [library ...]]
runs exec("from " + library + " import *") on each
library, beware of side effects
--pre [code [code ...]]
runs exec(code) for each line of code before
execution, beware of side effects
--post [code [code ...]]
runs exec(code) for each line of code after execution,
beware of side effects
-p int number of processes (be careful!)
-n, --norun prints commands without executing them
-v, --verbose prints commands
-w, --csv writes results to pyxargs-<yymmdd-hhmmss>.csv in
os.getcwd()
--examples print example usage
