comparing column of two different files and print the column from in order of 2nd file

Hi friends,

My file is like:

Quote:
A
D
F
E
B

Second file is :

Quote:
A
B
C
D
E
F
G
I need to print the rows present in file one, but in order present in second file....I used
Code:
 
while read gh;do
awk ' $1=="' $gh'" {print >> FILENAME"output"} ' cat listoffirstfile
done < secondfile

but the output I am getting is:
Quote:
A
B
D
E
F
Whereas, i want to print it like:

PHP Code:
A
B
ABSENT
D
E
F
ABSENT 
Can any one help me in using the above awk command such that it prints the required output.
# 2  
Try this

Code:
awk 'NR==FNR{_1[$0]++;next} {if(!_1[$0]){$0="ABSENT"} print }' file1 file2

regards,
Ahamed

Hi Ahamed,

that doesn't work.....
it is showing ABSENT for all the rows Smilie

whereas, i want to print it like:

Quote:
A
B
ABSENT
D
E
F
ABSENT
# 4  
Code:
awk 'NR==FNR{a[$0]++;next}{if ($0 in a){print $0}else{print "ABSENT"}}' file1 file2

# 5  
Code:
$ awk 'BEGIN { while(getline a<"file1") ARR[a]=1       }
        {       (ARR[$0]) || $0="ABSENT"        } 1' < file2
A
B
ABSENT
D
E
F
ABSENT
$

If file1 isn't in order, you have to store the whole thing to tell if lines are absent or present.
# 6  
Using basic unix shell commands:
Code:
#!/usr/bin/ksh
while read mStr; do
  mCnt=$(egrep -c ${mStr} File1)
  if [[ "${mCnt}" = "0" ]]; then
    echo "ABSENT"
  else
    echo ${mStr}
  fi
done < File2

# 7  
Hi all,

Thanx for the help.....

it is giving the correct output.... Smilie

Furthermore, what should I do if my first file is having multiple columns, like:

Quote:
fds 21 sdf 32 6432
kjh 54 lkj 45 4567
lkj 78 uio 56 5342
bnm 56 hfv 67 456
and i want to arrange my data as in second file:

Quote:
lkj
bnm
kjh
fds
and want to print the 5th row of first file, in the order present in second file

required output should be:

Quote:
5342
456
4567
6432
