Cmd-utils is a set of programs for making certain things more convenient from the windows command line. There are a lot of little gaps that the windows CLI has compared to bash, things like not having a great way to counte lines, or examine memory usage, or perform commands over file globs.
Use Powershell Core if you can. I've been convinced to use it more than stuff like this now.
If powershell works for you, great! For me, it tends to fall down a little bit in interactive use, or is a bit clunky at answering the questions I'm looking to answer. Hence, these utils.
First, you'll want to install Janet. Then clone this repo, and run jpm build. This will create a file called size.exe in the build folder. To install size, put size.exe on your %PATH%.
web-dir starts a static file server on port localhost:8000, reports Last-Modified, and sets CORS headers to allow SharedArrayBuffers to work in WASM code.
size is a small program for counting words, lines and bytes in a windows command prompt. It can be used on linux or osx, but is likely not needed there, due to the presence of wc.
type README.md | size should output something like:
Stdin was 19 lines, 112 words, and 705 bytes
-KB, -MB, and -GB will report sizes in kilobytes, megabytes and gigabytes respectively.
env-explode prints out delimited environment variables, one element per line.
run can be used to customize the environment a given command runs under. NAME=VALUE pairs set up the environment, the /CD or -cd flag changes to a different directory, and the -c or -cmd flag sets the command to be run. /SH has run use shell-execute, but it does not by default.
each is not unlike the unix find (as opposed to the windows find, which is more like the unix grep). It can iterate files, directories, PIDs, services, or numeric ranges.
each -g "*.js" -c "type %1"
mem scans over the output of tasklist.exe, tallying up memory totals. It can give you the output by exectuable name, by pid, or by session id. It's not a fancy program, but has helped me diagnose where my memory usage has been going.
mem by-name -MB
-KB, -MB, and -GB will report memory usage in kilobytes, megabytes and gigabytes respectively.
