I am having two .txt files with data stored in the format
1.txt
ASF001-AS-ST73U12
ASF001-AS-ST92U14
ASF001-AS-ST105U33
ASF001-AS-ST107U20
and
2.txt
ASF001-AS-ST121U21
ASF001-AS-ST130U14
ASF001-AS-ST73U12
ASF001-AS-ST92U14
` I need to find the files which are in 1.txt but not in 2.txt.
I tried to use
diff -a --suppress-common-lines -y 1.txt 2.txt > finaloutput
but it didn't work
Rather than diff you can use comm
here:
comm -23 <(sort 1.txt) <(sort 2.txt)
ASF001-AS-ST105U33
ASF001-AS-ST107U20
Or this awk
will also work:
awk 'FNR==NR {a[$1];next} $1 in a{delete a[$1]} END {for (i in a) print i}' 1.txt 2.txt
ASF001-AS-ST107U20
ASF001-AS-ST105U33
