bash break loop code example

Example 1: bash break for looop

break [n] #Exit optional given n number of loops

Example 2: shell loop terminating after command

The problem is that do_work.sh runs ssh commands and by default ssh reads from stdin which is your input file. As a result, you only see the first line processed, because ssh consumes the rest of the file and your while loop terminates.

To prevent this, pass the -n option to your ssh command to make it read from /dev/null instead of stdin.
