differentiating two sets for filenames????
set 1
./abc@@/main/61
./def.cpp@@/main/13
./fgh.cpp@@/main/16
./ijk.cpp@@/main/12
./mln.cpp@@/main/9
./uvw.cpp@@/main/30

set2
./eww@@/main/61
./def.cpp@@/main/13
./xxx.cpp@@/main/26
./kkk.cpp@@/main/72
./qqq.cpp@@/main/19
./fgh.cpp@@/main/16


I have two sets with filenames in above format.
need to o/p full filenames from the first set which are not present in second set.

Please note that filenames are considered similar only if they match till @@ symbol. Then only they should be considered similar.

Please guide me in this.

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

Hi

here are the input files
sett1
./cwhelper/tcwhelper.cpp@@/main/62

sett2
./cwhelper/tcwauthlatesettreqcreen.hpp@@/main/1
./cwhelper/tcwhelper.cpp@@/main/64


i have created cmp.awk as follows


#! /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

running like this

./cmp.awk sett1 sett2


but getting following error

/usr/bin/nawk: syntax error at source line 5
context is
awk >>> -F@ <<<
/usr/bin/nawk: bailing out at source line 5

remove the first line which contains "#! /usr/bin/nawk -f"

awk: syntax error near line 1
awk: illegal statement near line 1
awk: syntax error near line 1
awk: bailing out near line 1

what i pasted was a oneliner.
If you need this to keep in a file, do it as follows.

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

look at the '$' symbol

./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
