How do you run a command for each line of a file?

Question

For example, right now I\'m using the following to change a couple of files whose Unix paths I wrote to a file:

cat file.txt | while read in; do chmod 755 \"         


        

Answer 1

I know it's late but still

If by any chance you run into windows saved text file with \r\n instead of \n, you might get confused by the output if your command has sth after read line as argument. So do remove \r, for example:

cat file | tr -d '\r' | xargs -L 1 -i echo do_sth_with_{}_as_line
