Hi list,
Since the upgrade to 5.2, when I log into my server with a ldap account
I have these 2 errors messages:
-bash: [: =: unary operator expected
-bash: [: -le: unary operator expected
After investigation, the trouble come from two scripts in /etc/profile.d:
/etc/profile.d/krb5-workstation.sh
/etc/profile.d/vim.sh
The problem is with the test where the command "id" is involved, like:
if [ `/usr/bin/id -u` = 0 ] ;
If I add double quotes ("`/usr/bin/id -u`"), it will work again.
Indeed, as a connected ldap user, the id command returns nothing when
quoted:
[ldapUser@server ~]$ /usr/bin/id -u
12345
[ldapUser@server ~]$ `/usr/bin/id -u`
[ldapUser@server ~]$
As a normal user, the command behaves normally:
[user@server ~]$ `/usr/bin/id -u`
-bash: 1302: command not found
[user@server ~]$ /usr/bin/id -u
1302
I have modified theses two scripts but I am afraid it will break
something in the future.
Any idea on how to resolve this cleanly ?
Best regards,
kfx
