Well I didnt see a forum for bash scripting, so I figured this was the closests to it. I've been using the this string for awhile now without problems until today.

Code:

Intfa=`cat /home/user/config.ini | grep -m 1 "Intf=" | sed 's/^[Intf=]*//'`; echo "$Intfa"

Code:

[root@Hostname ~]# Intfa=`cat /home/user/config.ini | grep -m 1 "Intf=" | sed 's/^[Intf=]*//'`; echo "$Intfa"
123.456.789.100
[root@Hostname ~]#

Now that echo's it perfectly

But when I go to use it in my script, It gets all funky, I have narrowed it down to this script. When you add spaces at the end of the variable inside the quotes, it does this.

Code:

[root@Hostname ~]# Intfa=`cat /home/user/config.ini | grep -m 1 "Intf=" | sed 's/^[Intf=]*//'`; echo "$Intfa   "
   .456.789.100
[root@Hostname ~]#

For some reason, how ever many spaces or charectors I put after the variable, it places it at the begining, another example is:

Code:

[root@Hostname ~]# Intfa=`cat /home/user/config.ini | grep -m 1 "Intf=" | sed 's/^[Intf=]*//'`; echo "$Intfa is the IP"
 is the IP9.100
[root@Hostname ~]#

This is the first time this has ever happened, I'm stumped.

Common Answers from other people trying to help:

Dont put the var in quotes while echoing - I have to do this becuase its echoing the variable into another script.
Try to pass the variable to another script - I get the same result.
Use awk in the line - I get the same result.
Include the INI file in the script - Some of the other variables have spaces and do not have quotes (For example: Intf=123.456.789.100) so the variables get messed up if anything above the variable I need has spaces due to it not having quotes.


Any help on this is greatly appreciated. Thanks.

I'm a perl guy so excuse me if I'm just wrong on the face of it.

s/^[Intf=]*//

should you be using square brackets in the above substitution?

Have you tried:

s/^(Intf=)*//

or

s/^Intf=//

I've also tried without the sed, same result.

Well, maybe go over to www.tek-tips.com and find the Unix shell scripting forum and ask over there.
