Bug ID: 20339
Summary: wordexp(3) fails for (certain) names (with single
quotes and spaces)
Product: glibc
Version: 2.23
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: steffen at sdaoden dot eu
CC: drepper.fsp at gmail dot com
Target Milestone: ---
While testing my new tab-completion and shell quoting i came along testing with
the files (UTF-8):
dräi dr$'\' c\cAa x.txt' drö' öge' drü' üe'
It doesn't seem to be possible to match the (unquoted) dr'..., i.e., to match
across the single quote:
name="/tmp/dr\\'";
fprintf(stderr, "GLOBBING <%s>\n",name);
..
i = wordexp(name, &we, WRDE_NOCMD);
..
switch(we.we_wordc){
case 1:
cp = savestr(we.we_wordv[0]);
fprintf(stderr, "MATCH <%s>\n",cp);
break;
..
This gives me:
GLOBBING </tmp/dr\'>
MATCH </tmp/dr'>
So it does find the one file that exists:
?0[steffen@wales tmp]$ ll dr\'*
-rw------- 1 steffen steffen 0 Jul 6 14:47 'dr'\'' c'$'\001''a x.txt'
But it seems to cut off the name after the space.
(While here: the quoting os ls(1) is hard to grasp, right?)
This is on a current ArchLinux:
?0[steffen@wales tmp]? pacman -Q glibc
glibc 2.23-5
