pgmcc=$?
if [[ $pgmcc != 0 ]]
then
echo "FATAL ERROR, TERMINATING NOW"
fi
In this case i'm just getting the error written in error_log as sort: A write error occured while sorting.
But i want to capture error which comes on the console something like below:
vxfs: msgcnt 5980 mesg 001: V-2-1: vx_nospace - /dev/vx/dsk/drd_rootdg/tmpvol file system full (2 block extent)
Is there a way if i can achieve the above...??
No. The vxfs error message is not being written by sort; it is a diagnostic message being written to the console by the operating system. The
2>>errlog will append diagnostics written by sort to errlog, but can't capture messages written to the terminal by the operating system nor by unrelated processes.
Your system probably has a log file where error messages written to the console are saved (but if the filesystem where the log files would be written is full, the message might only appear on the screen). Where those log files are kept is system specific.

look(1) General Commands Manual look(1)
NAME
look - Finds lines in a sorted list
SYNOPSIS
look [-df] [-tcharacter] string [file]
The look command prints all lines in a sorted file that begin with string.
OPTIONS
Uses dictionary order; only letters, digits, tabs, and spaces are used in comparisons. Searches without regard to case; treats uppercase
and lowercase as equivalent. Ignores character and characters following it in the search string. If you specify look -tC ABCDE, the
string ABCDE would become (in effect) AB, with CDE being ignored. This option is primarily for shell scripts, in which more than one
string is being processed.
DESCRIPTION
If no file is specified, look searches in the system word list /usr/share/dict/words, with the options -df assumed by default.
The look command uses binary search.
The -d and -f options affect comparisons as in sort.
NOTES
In order to use the -f option, you must first sort file with the sort -f command; otherwise, look displays only lowercase items.
If you do not specify -f, but specify a file (such as /usr/share/dict/words) that has been sorted with sort -f, look may not produce any
output.
EXAMPLES
To search a sorted file called sortfile for all lines that begin with the string as, enter: look as sortfile To search the system word list
for all words beginning with smi, enter: look smi
This might result in: smile smirk smith smithereens Smithfield Smithson smithy smitten
FILES
System word list.

Commands: grep(1), sort(1), spell(1)
