How to make nawk to set a shell variable

rakeshou · #1 (**permalink**) 10-17-2007

Below is the content of the file I am parsing

Code:

bash-2.03$ cat rakesh
cpio: Cannot write "reloc/lib/gcc-lib/i386-pc-solaris2.7/2.95.2/gmon.o", errno 28, No space left on device
cpio: Cannot write "reloc/lib/gcc-lib/i386-pc-solaris2.7/2.95.2/include/README", errno 28, No space left on device
cpio: Cannot write "reloc/lib/gcc-lib/i386-pc-solaris2.7/2.95.2/include/assert.h", errno 28, No space left on device
cpio: Cannot write ", errno 28,


pkgadd: ERROR: attempt to process datastream failed
    - process </usr/bin/cpio -icdumD -C 512> failed, exit code 86
pkgadd: ERROR: unable to unpack datastream

Installation of <SMCgcc> failed (internal error).
No changes were made to the system.

Here I set the variable STATUS=5

Code:

bash-2.03$ STATUS=5

then execute this command, where I set the Shell variable STATUS=1

bash-2.03$ cat rakesh | nawk -F"," 'BEGIN{spaceError=0;}{if($2==" errno 28"){system("export STATUS=1");spaceError=1;print $0 ": ERROR"} else {print $0;}}END{if(spaceError==1)system("banner \"No space\"");}'

#     #   ####            ####   #       #    #   ####   ######

Check if STATUS got set.

Code:

bash-2.03$ echo $STATUS
5

No

The command system("export STATUS=1"); doesn't seem to work.

I want to chech if STATUS=1, If yes, I want to display a custom error message.

Please help

Thanks

Perhaps just use "exit spaceError" as the last command in your awk script. Then in the shell script do "export STATUS=$?" immediately after the awk.
