Replace text in parentheses


I would like to replace a comma in parentheses to a semicolon for example. Other commas outside () stay unchanged. How can I do this?

Hope this works for you.
awk -F"," '{print $1,",",$2,",",$3,",",$4,";",$5,";",$6,",",$7,",",$8}' file1 | sed 's/ //g'
sed is used to avoid spaces between "," (Commas)

If in the string there is only a couple of open/closed parenthesis:

echo "aaaa,bbb,ccc,ddd(eee,fff,ggg),hhh,iii" | \
awk -F'[()]' '{ gsub(",",";",$2); print($1"("$2")"$3) }'

This is a rapid solution. For sure there will be a more clever and general method to obtain the same Smilie

Thanks a lot
The text in file can be dynamic.

Another quick and dirt one:
awk '{
   for (i=1; i<=length($0); i++) {
      if (c == "(") replace=1;
      if (c == ")") replace=0;
      if (c == "," && replace) { s=s";" } else { s=s c };
   print s;
}' input_file

However, it doesn't work if you have unmatched parenthesis on lines!

awk string function


We can use awk string function GSUB to address this issue.


nawk 'BEGIN{FS="[()]"}
printf("%s(%s)%s\n", $1,$2,$3)
}' file
