match patterns update output file uncomment when desired
- by user2692634
Need suggestion for following. Have two files myfile and responsefile.
First file
myfile.txt
user=myname
user_1=yourname
group=mygroup
group_1=yourgroup
second file
responsefile.txt
#Please fill details
user=
#user_1=
#user_2=
#Please fill details
group=
#group_1=
#group_2=
Based on myfile.txt data update responsefile.txt as below and the file responsefile.txt is lenghty of about 604L, 16481C.
Result output
responsefile.txt
#Please fill details
user=myname
user_1=yourname
#user_2=
#Please fill details
group=mygroup
group_1=yourgroup
#group_2=
If you observe myfile above, I want to match user= in responsefile, then update as user=myname, same applies for group=. Then match user_1= and group_1= which is hashed or commented in responsefile, update as user_1=yourname and group_1=yourgroup. Should not remove hash or uncomment for others in file.
I tried this
awk -F= 'NR==FNR{a[$1]=$0;next}$1 in a{$0=a[$1]}1' myfile.txt responsefile.txt
Please suggest thanks in advance.
