What Is the Linux Equivalent to Dos Pause

What is the Linux equivalent to DOS pause?

read does this:

user@host:~$ read -n1 -r -p "Press any key to continue..." key
[...]
user@host:~$ 

The -n1 specifies that it only waits for a single character. The -r puts it into raw mode, which is necessary because otherwise, if you press something like backslash, it doesn't register until you hit the next key. The -p specifies the prompt, which must be quoted if it contains spaces. The key argument is only necessary if you want to know which key they pressed, in which case you can access it through $key.

If you are using Bash, you can also specify a timeout with -t, which causes read to return a failure when a key isn't pressed. So for example:

read -t5 -n1 -r -p 'Press any key in the next five seconds...' key
if [ "$?" -eq "0" ]; then
    echo 'A key was pressed.'
else
    echo 'No key was pressed.'
fi

Looking to get a timeout/wait command in linux equivalent to ms-dos

Use this:

sleep 3

so, just use sleep and the given time in seconds.

pause function not working in script that worked in previous server CentOS 9

The error message is from your source command. Where did variables.sh come from? You probably need to use the full path name.

Your first line has an error, there should not be a space between the # and the !, it should be #!/bin/bash (optional space after the !).

The backticks are unnecessary around the function, and the syntax is either:

function pause { ... }

or

pause() { ... }

not both, although that should not generate an error.

Pause programmatically video player mpv

To control mpv remotely (eg from another terminal session) you can also start it with the option

--input-ipc-server=/tmp/mpvsocket

and control it by issuing commands like this:

echo '{ "command": ["set_property", "pause", true] }' | socat - /tmp/mpvsocket

See man mpv for (many) more details.

edit: see also mpv --list-properties

edit2: The most simple way I've found to "toggle" pause/play is

{"command": ["cycle", "pause"]}

I'm looking to convert my MS-DOS .bat file into the equivalent linux .sh file

function choice1 {

echo "Do stuff here to create an account"

}

function choice2 {

echo "Get the point?"

}

function choice3 {

exit

}

#### Main

echo "Welcome to OP-SYS Account creation. Please choose which mode you would like to continue in."
echo

echo "[1] Basic Account Creation
[2] Advanced Account Creation
[3] Exit"
echo

read CHOICE #### This loads your choice into a variable

eval choice"$CHOICE" ### This is evaluation awesomeness
