[awk] Simple things not working on Solaris 10

Shell Programming and Scripting
1

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:

# 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:

# 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:

nawk '{last=$NF} END{print last}' infile
3

Try:

/usr/xpg4/bin/awk '{.....}' file
4 
nawk '{last=$NF} END{print last}' infile

That is indeed working.

What about the other example ?

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

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

Is not working.
Same result.

Try:

nawk -F: '{last=$1} END{print last}' infile

The 'trick' is to save the fields one wants use in the end clause in the beginning.
Example:

nawk '{f1=$1; f2=$2; f3=$3} END{print f1, f2, f3}' infile
