Manually iterating a line of a file | bash

Question

I could do this in any other language, but with Bash I've looked far and wide and could not find the answer. I need to manually increase `$line` in a script. Example: ``` for line in `cat file` do foo() foo_loop(condition) { do_something_to_line($line) } done ``` If you notice, every time the `foo_loop` iterates, `$line` stays the same. I need to iterate `$line` there, and make sure the original for loop only runs the number of lines in file. I have thought about finding the number of lines in file using a different loop and iterating the line variable inside the inner loop of `foo()`. Any ideas? EDIT: Sorry for being so vague. Here we go: I'm trying to make a section of my code execute multiple times (parallel execution) ``` Function foo() # Does something for line in `cat $temp_file`; foo($line) ``` That code works just fine, because `foo` is just taking in the value of line; but if I wanted to do this: ``` Function foo() # Does something for line in `cat $temp_file`; while (some co…

Accepted Answer

Instead of using a for loop to read through the file you should maybe read through the file like so.

#!bin/bash

while read line
do
    do_something_to_line($line)
done < "your.file"
```
