Shell Programming and Scripting

Hi,
I'm trying to replace a string with the contents of a file.. I found the below thread that shows how to do this but is there any way to use a variable as the file name in the nawk command?.. When I try I get an error saying

Code:

        while read groupsvar
        do      
                replacevar="%${groupsvar}"

                nawk -F"$replacevar" 'NF>1{printf "%s",$1;\
                for (i=2;i<=NF;i++){system("cat ${groupsvar}_temp");printf "%s",$i ((i==NF)?"\n":z)}}NF==1' 
${entries} > ${entries}_1001
        done < ${grouplist}_temp2

https://www.unix.com/shell-programmin...strings-2.html

Code:

"cat ${groupsvar}_temp"

...
cat is giving the error message, meaning ${groupsvar} is null or not initialized correctly... and so cat is trying to open _temp that does not exist...

But if I echo out ${groupsvar} after the do it is returning the correct data..

The AWK script is a single-quoted string. There is no shell parameter expansion occurring within it, so the variable isn't replaced in the script before AWK is executed. Further, the shell spawned by the system command has no notion of that variable as it has no access to it via the command line nor its environment.

If you instead provide a sample of the data in those files along with the desired result and what you're trying to accomplish, we can probably guide you towards a solution that is less convoluted.

What OS and shell are you using?

Using ksh and its solaris.. In the end i just did the below and it got around it..

Code:

groupsvar1=$SUDOREP_WORK/$groupsvar; export groupsvar1

However its not what I hoped it would be...


What I'm trying to do is replace the group names (which are identified with a % sign in front of them) in the last field of the AIX_vintella.sudoers_entries file attached with their actual user id and name...

I've managed to dump the user id's and names into a separate file for each group.. Like the webstaff_temp file attached..

I was using a list file (AIX_vintella.sudoers_grouplist_temp2) to try and cycle through each group and replace the match in the *entries file..

But alas it doesn't work properly and I don't know what direction to go any more with this...
