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

You can also use AWK which can give you more flexibility to handle the file

awk '{ print "chmod 755 "$0"" | "/bin/sh"}' file.txt

if your file has a field separator like:

field1,field2,field3

To get only the first field you do

awk -F, '{ print "chmod 755 "$1"" | "/bin/sh"}' file.txt

You can check more details on GNU Documentation https://www.gnu.org/software/gawk/manual/html_node/Very-Simple.html#Very-Simple
