Top Forums Shell Programming and Scripting Compare Only "File Names" in 2 Files with file lists having different directory structure Post 302988624 by Don Cragun on Friday 30th of December 2016 02:32:53 AM

I don't see that greet_sed's suggestion makes any attempt to extract just the last component of any of the pathnames in your two files. You didn't show us how your tar archives are created and you haven't bothered to tell us what operating system or shell you're using. The following awk script should work even if your archives contain directories in addition to regular files, but if your archives only contain regular files, the code could be simplified:
Code:
awk -F/ '
!$NF {	next
}
NR == FNR {
	files[$NF]
	next
}
{	delete files[$NF]
}
END {	for(file in files)
		print file
}
' arch_all combined

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk or nawk.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
