Invoking external command lines (utilities) is broken with respect to quoting on Unix #3734
Description
Related: #3733
Steps to reproduce
/bin/sh -c "echo 'hi, mom'"
/bin/sh -c 'echo "hi, mom"'Expected behavior
hi, mom
hi, mom
Actual behavior
hi, mom
hi,
The following literals should be passed through to sh (there's nothing for PowerShell to interpret here):
echo 'hi, mom'
echo "hi, mom"
To a POSIX-like shell, these two commands are equivalent (not generally, but with the given strings).
Unexpectedly, in the case of the 2nd command, 2 arguments are passed ($<n> represents the n-th positional parameter):
$1=[echo hi,]
$2=[mom]

Am I wrong, or is this a duplicate of #1995 and #3049 ?
I hope that this will be solved, RFC:

TSlivede you're right, resolving as dupe and making the original higher priority
