Replacing all commas with spaces - S/R with a Unix Command?

Question

I'm looking for a Unix command that will allow me to search/replace in a file - I need to replace all commas in a certain file with spaces. I need to do this in a script and I'm looking to avoid parsing/reading the file line by line. Is there a simple unix command that will allow me to do this?

Answer 1

I would suggest awk, in case you also need to expand your command with some conditionals (take a look here)

awk '{gsub(",", " "); print}' file_path > resultfile_path

Answer 2

sed 's/,/ /g' filename >resultfile

Answer 3

You can use awk, sed, vi, ex or even Perl, PHP etc ... depends what you are proficient with.

sed example:

sed -i 's/,/ /g' filename_here
