How about
$ awk -F, 'NR==FNR a[$1]; next $1 in a print; delete a[$1]' file1 file2
foo,1
boo,1
add a comment |
A variation of the famous seen idiom.
awk -F, 'FNR==NRa[$1]=1;next a[$1]++==1' file1 file2
add a comment |
Not actually awk
, but it works. And I suppose it allows for easy extension.
#!/usr/bin/env bash
while IFS= read -r line; do
grep -m1 "$line" "$2"
done < "$1"
$ ./script.sh file1 file2
Took the reading line-by-line from https://stackoverflow.com/questions/10929453/read-a-file-line-by-line-assigning-the-value-to-a-variable.
Then it's just 'find first match with content of line in file2'

awk -F "," 'NR==FNRa[$1];next($1 in a)print $0' file1.txt file2.txt| awk -F "," 'if (!seen[$1]++)print '
