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 \"

The logic applies to many other objectives. And how to read .sh_history of each user from /home/ filesystem? What if there are thousand of them?

#!/bin/ksh
last |head -10|awk '{print $1}'|
 while IFS= read -r line
 do
su - "$line" -c 'tail .sh_history'
 done
