Bug ID: 256473
Summary: FreeBSD shells are case insensitive for character
ranges
Product: Base System
Version: 12.2-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: bugs@FreeBSD.org
Reporter: jwb@freebsd.org
When running /bin/tcsh or /bin/sh, character ranges of either upper case or
lower case also expand to files with the other case:
FreeBSD moray.acadix bacon ~ 1017: ls -d [A-Z]*
Biostar/ Grad-school-biosci/ Save/
Books/ igv/ scripts/
Coral@ Moto/ VirtualBox VMs/
Data/ ncbi/ wpa_supplicant.conf
Desktop/ Ports/
Documents/ Prog/
FreeBSD moray.acadix bacon ~ 1018: bash
Using bash from ports, I do not see this behavior:
[bacon@moray ~]$ ls -d [A-Z]*
Biostar Data Grad-school-biosci Prog
Books Desktop Moto Save
Coral Documents Ports VirtualBox VMs
Also checked tcsh on a CentOS system and did not see this behavior.
Lastly I do NOT see this behavior from glob(3), so it seems to be limited to
shells in the FreeBSD base.
#include <stdio.h>
#include <sysexits.h>
#include <glob.h>
#include <unistd.h>
int main(int argc,char *argv[])
{
glob_t g;
g.gl_offs =3D 2;
glob("[A-Z]*", GLOB_DOOFFS, NULL, &g);
g.gl_pathv[0] =3D "ls";
g.gl_pathv[1] =3D "-d";
execvp("ls", g.gl_pathv);
return EX_OK;
}
