HowTo: Add Pause Prompt In a Shell Script ( bash pause command )

Most of you may be aware of old good DOS/2000/XP pause command. It is used display the prompt while suspending processing of a batch script. It is used within a computer batch file and allows the computer to pause the currently running batch file until the user presses any key.

bash pause command - under Linux / UNIX

There is no pause command under Linux/UNIX bash shell. You can easily use the read command with the -p option to display pause along with a message:

 
read -p "Press [Enter] key to start backup..."
 

The above will suspends processing of a shell script and displays a message prompting the user to press [Enter] key to continue.

bash shell pause function

You can create a function as follows:

 
#!/bin/bash
# init
function pause(){
   read -p "$*"
}
 
# ...
# call it
pause 'Press [Enter] key to continue...'
# rest of the script
# ...
 

Original DOS/XP pause command is an internal command. Use above technique if you are migrating from DOS/Windows batch file scripting.

    What about SLEEP command?

  • nixCraft March 5, 2007, 2:46 pm

    Sleep puts a delay for a specified amount of time w/o a prompt. So you need to use read –p so that user can hit a key.

    One small tip,
    If you do this in a while loop that reads from a file.
    e.g.
    while read line
    do
    …..
    read -p somevar
    …..
    done < somefile

    It will not work as expected, as the input for the while loop is “somefile”, so the “read -p ” inside the loop will read a line from somefile, instead of standard input.

    To solve this you can use file descriptors.

    so

    exec 5

    If you need an exact replacement for PAUSE you need to use:
    read -n 1 -p prompt
    without -n, read will require the ENTER key.
    I’m not sure but -n may be a bash specific.

    read -p “Press any key”. doesn’t provide the ‘pause’ behavior.

    It requires ‘ENTER’ key to be pressed, so it becomes, ‘press ENTER key’ instead of ‘press any key’.

      Thank you. I learned that the not so hard way. Trying it. :)

  • anders November 5, 2007, 5:21 pm

    Using simply read to pause>nul can be quite useful too.

    I ran into the need for pause in this simple bash script, where I pass a website as argument and the script tells me the password to the site from my personal password file. Note: one site and one password on each line, file mode should be 600.
    The script is useful to have on my webserver which is always on and I can reach from work or anywhere whenever I need it.

    #!/bin/bash
    cat ~/my_passwords.txt | grep $1; read; clear;

    Hope this helps someone :-)

    Lifesaver. Thankyou. :)

    (I needed to put in a “are you sure” message for windows users to be able to run scripts on a Linux box… who knows if it will help, but hey, at least it’s a start.)

  • LeMMiNGS June 23, 2008, 2:35 am

    Cool to know that that works out aswell!!

  • Diven August 22, 2008, 12:23 am

    I believe the following is at least very close to the behavior of the pause command.


    function pause(){
    read -s -n 1 -p "Press any key to continue . . ."
    echo
    }

  • christ December 9, 2008, 1:18 am

    read is a good choice for pausing but, sometimes we are looking for - pause then continue command without user interference so i guess sleep is more realiable

  • g00ner December 30, 2008, 11:17 am

    Being a windows admin this was of great help.

  • Pai March 18, 2009, 10:25 am

    echo “Press any Key to continue”
    read -n1 -t5 any_key

    -n1 -> number of character it can read
    -t5 -> it will wait for 5 seconds the user to enter a char after 5 sec it will resume the flow

  • Sanchit January 4, 2010, 12:56 pm

    Hi,
    I have one unix script file that has one command to execute a java program. That Java program is used to download a file from a server. After this command I have different commands (“hdiutil checksum -type CRC32 “) to execute on the downloaded file. My problem is that after executing the java command it is not waiting for the file to be downloaded from the server and executing that command and fails because still that file is not downloaded.

    Can someone help me to resolve this issue. How should I wait fro the file to be downloaded then only it should execute the other commands?

    Please help me to get out in to this situation as soon as possible…

  • tom3k February 10, 2010, 12:06 pm

    for anyone writing any cli based php scripts, and who doesnt feel like installing the whole ncurses package JUST to get the ‘press enter to continue…’ functionality…

    this method works great via

    system(‘read…..

    thanks! +5

  • JW August 7, 2010, 7:32 pm

    Thanks for script, I put it at the end of a function and it is helpful. How would I call a function when Enter is pressed? I tried the following but it didn’t work:

    function pause(){
    read -p “$*”
    Function_1
    }
    pause “Enter to continue…”

  • zulkaif dilawar May 27, 2011, 6:08 am

    I want to write a program which pause execution when i enter “return key ” and start execution when i again enter “return key ” from where it is paused.
    Please help me.

  • roger July 16, 2011, 1:39 am

    Thanks worked perfectly. Wonder why they don’t have this as a bash command…

  • Augustus July 26, 2011, 5:45 pm

    The code worked except the comment should read “Press the ENTER key to continue…”.
    Thank you!

  • Bhanu October 23, 2011, 7:46 pm

    This code worked for me well!

    I am looking to pause the script multiple times. So, I used multiple pause statements after every 10 lines. It didn’t work.

    Does anyone know why?

    Thanks.

  • Spaldam February 4, 2012, 6:53 pm

    It’s not working for me. I’m not sure why. The loop just keeps going.

  • epileg March 2, 2012, 8:50 pm

    There is a way to cleanly do that on Linux:

    #!/bin/sh

    echo -n “Press any key to continue…”
    stty -echo
    dd count=1 1>/dev/null 2>&1
    stty echo
    echo

    Best regards,

  • epileg March 2, 2012, 9:40 pm

    Sorry, previous one don’t properly works.
    This do the job:

    #!/bin/sh

    echo -n “Press any key to continue…”
    CFG=`stty -g`
    stty -echo -icanon
    dd count=1 1>/dev/null 2>&1
    stty $CFG
    echo

    Regards,

  • epileg March 2, 2012, 10:45 pm

    And a simple way:

    #!/bin/bash

    read -s -n 1 -p “Press any key to continue…”
    echo

    Regards,

  • echo November 1, 2012, 12:27 am

    What about SLEEP command?

  • Unix Macher March 25, 2015, 3:13 pm

    Doesn’t work on Debian 7, waste of time…
