quickbench - quick & easy benchmarking of command-line programs
quickbench [options] [<cmd>...]
Runs some test commands, possibly with different executables, once or more and shows their best execution times in tabular format.
Commands are specified as one or more quote-enclosed arguments, and/or one per line in CMDSFILE; or read from a default file [./bench.sh].
With -w, commands' first words are replaced with a new executable (or multiple comma-separated executables, showing times for all).
-f, --file CMDSFILE
: file containing commands, one per line (- for stdin)
-w, --with EXE[,...]
: replace first word of commands with these executables
-n, --iterations=N
: run each test this many times [default: 1]
-N, --cycles=N
: run the whole suite this many times [default: 1]
-p, --precision=N
: show times with this many decimal places [default: 2]
-v, --verbose
: show commands being run
-V, --more-verbose
: show command output
--debug
: show debug output for this program
-h, --help
: show this help
$ quickbench 'sleep 1'

$ quickbench -w echo,expr -p5 -n100 -N2
Running 1 tests 100 times with 2 executables at 2016-10-16 23:57:34.387764 UTC:
Best times 1:
+-------------++---------+---------+
| || echo | expr |
+=============++=========+=========+
| 3 * 1000000 || 0.00112 | 0.00135 |
+-------------++---------+---------+
Best times 2:
+-------------++---------+---------+
| || echo | expr |
+=============++=========+=========+
| 3 * 1000000 || 0.00111 | 0.00136 |
+-------------++---------+---------+quickbench looks for tests in ./bench.sh if no command arguments or
--file option are provided.
quickbench tests executable files on disk only, not shell builtins or aliases.
Options must precede arguments on the command line.
-V will become -vv when implementing that becomes easier.
