Hi

Am having 2 files

1st file having

1 2 3 4 5 6 7 8 9

2nd file
1
2
b
3
c

i want to check eache character in 2nd file is present or not
need to check whether 1 is present in 1st file

rec=`cat 2nd file`
for i in $rec
if [ $i = 1st file (how to check using array concept?

2

So your 1st file has only 1 row? if yes..

 
awk 'NR==FNR{v=$0;next}
v ~ $0{print $0"exists in 1st file"}' 1stfile 2ndfile
3

i want to print he character which is not present in the 1st file

4

change it as below..

 
awk 'NR==FNR{v=$0;next}
v !~ $0{print $0"exists in 1st file"}' 1stfile 2ndfile
5

A small correction :slight_smile:

awk 'NR==FNR{v=$0;next}
v !~ $0{print $0,"exists not in 1st file"}' 1stfile 2ndfile

b exists not in 1st file
c exists not in 1st file

hi jote

thank you

i want to execute in loop i need the condition like

if a in (2nd file a b c d.....)

then
echo string is correct
else echo string in not in 2nd file

fi

Is there any specific reason for loop? I guess awk fits the purpose (as per your details). Are we missing anything here?

yes

am writing a script to identify whether the string is present or not

for example

consider a record
abcd,1234,xyz

i need to validate whether the first column delimeter as , abc

is present in the array (a b c d e f)

if it is present then no issue else i need to print tha string

yes

i need to find the character which is nt present there will be many records

The delimiter , will never be present in the array (a b c d e f). I'm not sure what you were expecting.
