Shell Programming and Scripting

am also using bash and it is working fine for me.

pls check whether awk line is broken

Its strange
all awk line is single. even then following error

/home/odyssey/f091018>./cmp.awk sett2 sett1
awk: syntax error near line 1
awk: illegal statement near line 1
awk: syntax error near line 1
awk: bailing out near line 1

are you using any line like #!/bin/bash or something.
don't know why not working for me?????

Using following line in start
#! /usr/bin/nawk -f
first_file=$1
second_file=$2

awk -F@ '{ if (FNR==NR) { a[$1]=0; next } if ($1 in a) { a[$1]=1 } } END { for ( i in a ) { if (a[i]
==0) { print i } } }' $first_file $second_file


Errors are

/home/odyssey/f091018>./cmp.awk sett2 sett1
/usr/bin/nawk: syntax error at source line 5
context is
awk >>> -F@ <<<
/usr/bin/nawk: bailing out at source line 5

first line is not required.

Don't have any clue. Someone else has to bump.

Can you please paste your awk script and sett1 and sett2 contents???
Also the way you are using ????

sett1:

./cwhelper/tcwhelper.cpp@@/main/62

sett2:

./cwhelper/tcwauthlatesettreqcreen.hpp@@/main/1
./cwhelper/tcwhelper.cpp@@/main/64

cmp.awk:

first_file=$1
second_file=$2

awk -F@ '{ if (FNR==NR) { a[$1]=0; next } if ($1 in a) { a[$1]=1 } } END { for ( i in a ) { if (a[i] ==0) { print i } } }' $first_file $second_file

./cmp.awk sett2 sett1

output:

./cwhelper/tcwauthlatesettreqcreen.hpp

Strange !!!!
everything same. whats the error with me ???
In other awk scripts i had used #! /usr/bin/nawk -f and they are working fine. whats the problem with this script????
