In a Bash script, if you want to run multiple commands with nohup without combining them into a single string, you can use one of these approaches:

---

1. Group Commands with Braces

Use { } to group commands and redirect output for the entire group:

bash
Copy
nohup {
    command1
    command2
    command3
} > output.log 2>&1 &

• { } groups the commands, and the output of all commands is redirected to output.log.
• The & at the end runs the group in the background.

Note: There must be a space after { and before }.

---

2. Use a Subshell

You can also use ( ) to run the commands in a subshell:

bash
Copy
nohup (
    command1
    command2
    command3
) > output.log 2>&1 &

• This achieves the same result as braces but runs the commands in a subshell.

---

3. Separate nohup for Each Command

If you want each command to have its own nohup and output file:

bash
Copy
nohup command1 > output1.log 2>&1 &
nohup command2 > output2.log 2>&1 &
nohup command3 > output3.log 2>&1 &

• Each command runs independently, with its own output file.

---

4. Use a Function

Define a function and call it with nohup:

bash
Copy
my_commands() {
    command1
    command2
    command3
}
nohup my_commands > output.log 2>&1 &

---

Key Points:

• > output.log 2>&1 redirects both stdout and stderr to output.log.
• The trailing & runs the process in the background.
• Avoid using a string (e.g., nohup "command1; command2") as it can cause parsing issues.
