Sed for selective pattern replacement
Hi

I am having a code snippet

Code:
grant permission to all user
sts|ln|uSe|PSG
sajncht|se|Use|PPSPSG
psg|ln|use|TSPSG
sts_user.Me revoke

I need to change all occurance of use (uSe,Use,use) with USE. I am using the following sed command for this

Code:
sed 's/[uU][sS][eE]/USE/g' s_sample.txt

Output:

Code:
grant permission to all USEr
sts|ln|USE|PSG
sajncht|se|USE|PPSPSG
psg|ln|USE|TSPSG
sts_USEr.Me revoke

Whereas desired output is as follows

Code:
grant permission to all user
sts|ln|USE|PSG
sajncht|se|USE|PPSPSG
psg|ln|USE|TSPSG
sts_user.Me revoke

It has to be done with a shell script. If somebody can provide a sed command it would be a gr8 help.

Thanks

jazipconfig

JAZIPCONFIG(8)						      System Manager's Manual						    JAZIPCONFIG(8)

NAME

       jazipconfig - jazip(1) configuration tool.

SYNOPSIS

       jazipconfig [--non-interactive]

DESCRIPTION

       The jazipconfig script is a tool to easily build the /etc/jazip.conf file for the configuration of jazip(1)

OPTIONS

       The  optional  --non-interactive  command  line	parameter  instructs jazipconfig to do what it can to build a /etc/jazip.conf file without
       prompting the user.  On Debian systems, the command is invoked this way by the jazip package post-installation script.

       In this non-interactive mode, the script looks through /proc/scsi/scsi for detected Zip or Jaz devices.	 If  it  find  any,  it  looks	up
       /etc/fstab to see if it can find already specified mount points for them.  If (and only if) it finds mount points, it writes the device and
       mount point to /etc/jazip.conf

INTERACTIVE USE

       If no command line options are provided, jazipconfig runs interactively.  In this case, it also looks through /proc/scsi/scsi for  detected
       Zip or Jaz devices.  If it find any, it looks up /etc/fstab to see if it can find already specified mount points for them.  Then it creates
       a user menu which you can use to create the /etc/jazip.conf file.

NOTES

       The first entry listed in /etc/jazip.conf is the default device used when jazip is called without an argument.
