As not all environments have /dev/stdin. See ish-app/ish#944

Sorry ‘bout that.

Thanks for your contribution.
No need to be sorry about this!

Since our shebang points to Bash, I think this shouldn't be a problem. :)

@hyperupcall It’s not a bash thing, the device doesn’t exist in the OS:

iPad:~# echo whoami | bash -
root
iPad:~# echo whoami | bash /dev/stdin
bash: /dev/stdin: No such file or directory
iPad:~# uname -a
Linux iPad 4.20.69-ish SUPER AWESOME May 20 2023 23:41:32 i686 Linux

Note that since iSH (and CloudLinux) don’t support /dev based file descriptors, other common bashisms, such as process substitution, fail too:

iPad:~# cat < <(ls -1 /dev)
bash: /dev/fd/63: No such file or directory
iPad:~# cat <<<$(ls -1 /dev)
clipboard
console

location
null
ptmx

tty

@rasa I don't quite understand - your example code is not running under Bash. I don't expect echo whoami | bash /dev/stdin to work, but I expect bash -c "echo whoami | bash /dev/stdin" to work. The shebang of git-utimes points to bash, not sh. The manpage says that if the device does not exist on the OS, bash will "emulate it"?

your example code is not running under Bash.

It is, as cat < <(ls -1 /dev) is a bashism, that doesn't work in sh/ash/dash.

I see - perhaps I misread the Bash man page as those /dev/stdin files are not being used for redirection. The bash: /dev/fd/63: No such file or directory error does seems to suggest that this is being ran under Bash.

Thanks for the fix
