![What Does the Line '! /Bin/Sh -E' Do? [Closed]](https://docuprint.cloud68.co/uploads/what-does-the-line-bin-sh-e_1200.jpg)
In the beginning of a file on my server (linux), which is located in the /etc/init.d/ folder I have this line:
!/bin/sh -e
What does it mean, because every time I execute the rest of the script it works fine except for an error which shows:
!/bin/sh not found
Any ideas?

That line defines what program will execute the given script.
For sh normally that line should start with the # character as so:
#!/bin/sh -e
The -e flag's long name is errexit, causing the script to immediately exit on the first error. A more detailed description from man sh:
If not interactive, exit immediately if any untested command fails. The exit status of a command is considered to be explicitly tested if the command is used to control an
if,elif,while, oruntil; or if the command is the left hand operand of an&&or||operator.
#!/bin/bash
this is the first line in the script to tell the system to use bash shell to execute the script.
