UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.3
Patch Level: 46
Release Status: release
Description:
When using any functionality that triggers shquote the
comma character is escaped with a backslash which bash
doesn't strip when the quoted text is reused, while
tilde isn't despite it causing home directory expansion.
Repeat-By:
Run
echo $(printf "%q" "~" "a,b")
Expected output:
~ a,b
Given output
/home/scragar a\,b
Fix:
patching /lib/sh/shquote.c to have the bstab to have zero
for comma and a 1 for the tilde fixes this issue locally
