Description deanx 2010-01-06 18:43:22 UTC 
Description of problem:

tcsh-6.14-14.el5_4.2 introduced what seems to be a expansion issue when 'fgrep' is run under 'csh'. In particular wildcard expansion of 'fgrep' searches will fail. This may have serious issues of csh scripts.

How reproducible:

100% - see example

Steps to Reproduce:

1. do this in bash:  fgrep 'localhost' /etc/host*
  you should get something like:
/etc/hosts:127.0.0.1            localhost.localdomain localhost
/etc/hosts:::1          localhost6.localdomain6 localhost6

2. Switch to csh, $ csh
 
3.run it again: fgrep 'localhost' /etc/host*
 
You will not get any result.  This is errorneous, and used to work the same in both shells under prior version tcsh-6.14-14.el5.  You can get the same results with 'grep -F'  This is a problem whenever a * filespec is use
 
Actual results:

fgreg is returning empty results in 'csh'

Expected results:

fgrep should return same results in bash and csh


Additional info:

We have reverted tcsh to tcsh-6.14-14.el5 on the users system and the scripts are now running as before.
Comment 1 deanx 2010-01-06 19:42:15 UTC 
I shouldda also mentioned this too... the expansion is the problem:

under tcsh-6.14-14.el5;
command : $ echo fgrep 'localhost' /etc/host*

yeilds;
fgrep localhost /etc/host.conf /etc/hosts /etc/hosts.allow /etc/hosts.deny



under tcsh-6.14-14.el5_4.2;

command: $ echo fgrep 'localhost' /etc/host*

yields:

fgrep \l\o


Clearly tcsh-6.14-14.el5_4.2 has an issue here.
Comment 2 deanx 2010-01-07 13:46:18 UTC 
Additionally, tcsh also exhibits the same mal-behavior.
Comment 3 Garrett Holmstrom 2010-01-12 23:44:17 UTC 
This seems to be fixed in tcsh-6.14-14.el5_4.3.  Is there still more to do here?
