Compare two files

I need to compare two files:
Basically I have an input file fileA.
which need to be compare with fileB located in /etc/lc/mbd directroy

Both file format is like:

abc01def:10.80.11.123

The input file format is:

abc01mns:10.80.11.1
dbc02mns:10.80.11.2
fbc01mns:10.80.11.3
rbc01mns:10.80.11.4
tbc01mps:10.80.11.5
abt05mns:10.80.11.6
zbc11mys:10.80.11.7
ttc01mns:10.80.11.8
hbc05mns:10.80.11.9
qbc01mns:10.80.11.10

So after comparison the script will tell me:
what has been dupicate and what not duplicate.

Thanks

My preference is the comm command. From the manpages --

OPTIONS
     The following options are supported:

     -1       Suppresses the output column  of  lines  unique  to
              file1.

     -2       Suppresses the output column  of  lines  unique  to
              file2.

     -3       Suppresses the output column of lines duplicated in
              file1 and file2.

If you provide samples of both files, an example command could be created.

Thanks.,

This approach works, what do you think:

#!/bin/ksh
while read myline
do
cnt=0
while read line
do
if [[ "$myline" = "$line" ]]
then
((cnt+=1))
break
fi
done < file1
if [[ $cnt -eq 0 ]]
then
echo "$myline" >> output.file
fi
done < file2

But the problem here is suppose if i have one additional line in any file, it does not compare. It compares only with exact line numbers in each file.

you can try something like,

[ not tested ]

awk 'BEGIN{ while ( getline < "file_1" ) { arr[$0]++ } }{ if ( $0 in arr ) { printf "%s is duplicate\n", $0 } }' file_2

The diff command seems ideal for this. In particular:

diff -y file1 file2

This will give a side-by-side comparison. The man page lists more options than I've ever dreamed of using, but -y seems to answer your needs.

Try this, the result is stored in the files dup_file and no_dup_file:

awk 'NR==FNR{a[$0]=$0;next}
$0 in a {print $0 > "dup_file";next}
{print $0 > "no_dup_file"}
' fileA fileB

Use nawk or /usr/xpg4/bin/awk on Solaris.

Thanks, sdiff works, but I tried the above code but getting syntext error in line 2:

$ ./Comp2Files.awk
awk: syntax error near line 2
awk: bailing out near line 2

Just type the command on the prompt or use a script like this:

#!/bin/sh

awk 'NR==FNR{a[$0]=$0;next}
$0 in a {print $0 > "dup_file";next}
{print $0 > "no_dup_file"}
' fileA fileB

Replace the filenames with your filenames and if you get errors use nawk, gawk or /usr/xpg4/bin/awk on Solaris.
