    shellcheck.net is really helpful; it points out that you've set arr1 but are using arr_t – Jeff Schaller Aug 15 '16 at 14:08

    @Sangram, when you edit a post to remove all details, the details are still viewable in the edit history. If you are trying to prevent sensitive details from being publicly viewable, you shouldn't have posted them in the first place. I have flagged this question for moderator attention.

First of all, you really, really, really don't want to be doing this sort of thing in bash. There are tools that are specifically designed for this type of job and bash is very much not one of them. Attempting to do any but the most basic text parsing in bash is hard, error prone, and painful to read or write. It is also very slow.

Now, your specific error (please always include the exact error you are receiving) is:

/home/terdon/scripts/foo.sh: line 24:  : command not found

So the error is on line 24. Specifically, it is the space you have after the =:

str4= "$str1 $str3 $str2"

should be

str4="$str1 $str3 $str2"

You also have the same problem on line 25:

arr_t[$m]= $str4

should be


I suggest you ask a different question, explain what your script is trying to do and we can give you a saner approach than bashing your head against the wall like this.
