How to mark line in target file in case line matched - linux

Question

my bash script read each line from file - /tmp/file.CSV until EOF
And find if this line match line in other file - /tmp/target.CSV ( in case of full match bash script need to add "+" in the beginning of the matched line )
for example
line="/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11" ( from /tmp/file.CSV )
we see that $line have full match with line:
1,ull,LINUX,"/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11",fnt,rfdr,OK ( from /tmp/target.CSV )
then we need to add "+" on the line in /tmp/target.CSV as
+1,ull,LINUX,"/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11",fnt,rfdr,OK
please advice how to do that with sed or awk or maybe perl one liner in my bash script

my bash code
while read -r line
do
grep -iq "$line" /tmp/target.CSV
if [[ $? -ne 0 ]]
then
echo "$line" NOT MATCH target.CSV
else

done < /tmp/file.CSV

Answer 1

awk -F\" -v OFS=\" 'FNR==NR{ a[$0]++; next} $2 in a { $0 = "+" $0 } 1' file.csv target.csv
Output:
+1,ull,LINUX,"/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11",fnt,rfdr,OK
+2,Ama,LINUX,"/VPNfig/EME/EM8/Franlecom Eana SA/Amen",comrse,temporal,OK
+3,ArnTel,LINUX,"/VPConfig/EME/EM3/ArmenTem Armenia)/ArmenTe",Coers,FAIL
4,Ahh,LINUX,"/VPConfig/EMA/EM/llk/AAe",Coers,FAIL
Or
awk -F\" -v OFS=\" 'FNR==NR{ a[$0]++; next} { print ($2 in a ? "+" : " ") $0 }' file.csv target.csv
awk -F\" -v OFS=\" 'FNR==NR{ a[$0]++; next} { $0 = ($2 in a ? "+" : " ") $0 } 1' file.csv target.csv
Output:
+1,ull,LINUX,"/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11",fnt,rfdr,OK
+2,Ama,LINUX,"/VPNfig/EME/EM8/Franlecom Eana SA/Amen",comrse,temporal,OK
+3,ArnTel,LINUX,"/VPConfig/EME/EM3/ArmenTem Armenia)/ArmenTe",Coers,FAIL
4,Ahh,LINUX,"/VPConfig/EMA/EM/llk/AAe",Coers,FAIL
And this one is valid whether each line starts with a single space or not:
awk -F\" -v OFS=\" 'FNR==NR{ a[$0]++; next} { sub(/^ ?/, $2 in a ? "+" : " ") } 1' file.csv target.csv
Try
awk -F\" -v OFS=\" 'FNR==NR{ a[$0]++; next} { sub(/^ ?/, $2 in a ? "+" : " ") } 1' file.csv target.csv
Update (1)
awk -F, -v OFS=, 'FNR==NR{ sub(/[ \t\r]*$/, ""); a[$0]++; next} { t = $4; gsub(/(^"|"$)/, "", t); sub(/^[ \t]*/, t in a ? "+" : " "); } 1' file.csv target.csv
Output:
+1,ull,LINUX,"/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11",fnt,rfdr,OK
+2,Ama,LINUX,"/VPNfig/EME/EM8/Franlecom Eana SA/Amen",comrse,temporal,OK
+3,ArnTel,LINUX,"/VPConfig/EME/EM3/ArmenTem Armenia)/ArmenTe",Coers,FAIL
4,Ahh,LINUX,"/VPConfig/EMA/EM/llk/AAe",Coers,FAIL
+142,ucell,LINUX,/VPNAAonfig/EMEA/EM3/Ucell/ede3fc34,Glo,G/rvrev443,OK
Update (2)
awk -F, -v OFS=, 'FNR==NR{ sub(/[ \t\r]$/, ""); a[$0]++; b[FNR]=$0; next} { t = $4; gsub(/(^"|"$)/, "", t); r = " "; if (t in a) { c[t]++; r = "+" }; sub(/^[ \t]*/, r); } 1; END { for (i = 1; i in b; ++i) { t = b[i]; sub(/^[ \t]*/, t in c ? "+" : " ", t); print t > "/dev/stderr" } }' file.csv target.csv > new_target.csv 2> new_file.cs

Try this Perl's one liner:
perl -pi -e '$_="+".$_ if($_=~m{/VPNfig/EME/EM3/Ucll/ucelobeconn/6EKoHH11}is);' /tmp/target.CSV
