Matching and appending

Shell Programming and Scripting
1

I have two files

FILEA

a/b/c/d
e/f/g/h
i/j/k/l
m/n/o/p

FILEB

i/j/k/l

i want that if lines of FILEB matches lines of FILEA then matching lines in FILEA to be appended by word "MATCH"

NEW FILEA

a/b/c/d
e/f/g/h
i/j/k/l "MATCH"
m/n/o/p

I have tried following script .but not getting desired result.Please Help

for i in `cat FILEB`
do
  if [ `grep "$i" FILEA ]; then
    `sed '/$i/ s/$/ "MATCH" FILEA`
  fi
done

Try:

awk 'NR==FNR{a[$0];next}$0 in a{$0=$0 " MATCH"}1' FILEB FILEA > NEWFILEA
3 
# awk 'NR==FNR{a[x++]=$0}END{for(i=0;i<x;i++)if($0==a)print aFS"\"MATCH\"";else print a}' FILEA FILEB
a/b/c/d
e/f/g/h
i/j/k/l "MATCH"
m/n/o/p

Tried it.It is not generating any error message.But also not generating desired output

How about this ?

 awk 'NR==FNR{a[$0]++;next} a[$0]{$0=$0 FS "\"MATCH\""}1' FileB FileA

Yet another one:

awk 'NR==FNR{A[$0]="\"MATCH\""; next}{print $0,A[$0]}' FileB FileA

On Solaris use /usr/xpg4/bin/awk rather than awk

/usr/xpg4/bin/awk  'NR==FNR{A[$0]="\"MATCH\""; next}{print $0,A[$0]}' FileB FileA

Working.
