[awk] Simple things not working on Solaris 10
Hi,

Don't know if this is Solaris 10 or that the shell on Solaris 10 is working against me.
But this works fine on HP-UX 11i, but not on Solaris 10:

Code:
# cat /tmp/test_file
1:een
2:twee
3:drie
# cat /tmp/test_file | /bin/nawk 'END {print $NF}'

# cat /tmp/test_file | /bin/nawk '{} END {split($1,result,":");print result[1]}'

#

Also tried to use awk iso nawk.
And tried sh, ksh and bash.

Any ideas why this is not working ?

Here the HP-UX 11i output:

Code:
# cat /tmp/test_file | /bin/nawk 'END {print $NF}'
3:drie
#  cat /tmp/test_file | /bin/nawk '{} END {split($1,result,":");print result[1]}'

Not every awk keeps the value of $0,$1..$NF after the END clause... (This behaviour is unspecified by the standard) Try:
Code:
nawk '{last=$NF} END{print last}' infile

Try:
Code:
/usr/xpg4/bin/awk '{.....}' file

Code:
nawk '{last=$NF} END{print last}' infile

That is indeed working.

What about the other example ?

Code:
#  cat /tmp/test_file | /bin/nawk '{} END {split($1,result,":");print result[1]}'

Code:
/usr/xpg4/bin/awk '{.....}' file

Is not working.
Same result.

Perfect !
Thanks.

The 'trick' is to save the fields one wants use in the end clause in the beginning.
Example:
Code:
nawk '{f1=$1; f2=$2; f3=$3} END{print f1, f2, f3}' infile
