Make echo text appear to be typed

[Sub101]

I know this is a silly request and has no real need but i would like to have my echo text type out. That is to type each letter at a time. Is there a way to do this at all?

Thanks for your help

What language?

[OutOfReach]

I know very little to no bash (if I am correct this is the language you are talking about), but from past experiences (from other languages) I think you need to set a timer, or something along the lines of that.

Sorry, I completely forgot to say, using bash. Yeh i thought about maybe using



echo H
sleep 1
echo E
sleep 1
echo L
sleep 1
echo L
sleep 1
echo O

or something similar. I was just curious as to whether there was perhaps a similar method to making echo bold and that sort of thing. Thanks for the quick replies.

slowecho


#!/bin/bash
#
# slowecho -- a bash script that echoes its argument one character
# per second.
#
arg=${@}
for (( i=0; i < ${#arg}; i+=1 )) ; do
echo -n "${arg:$i:1}"
sleep 1
done
echo

E.g.


$ ./slowecho 'Hello, world!'
Hello, world!
$

See how the characters in the output were printed one per second? :)

That won't work in Ubuntu, which uses Dash as the default shell. Change it to #!/bin/bash.

[ghostdog74]

its already #!/bin/bash?

its already #!/bin/bash?

I see it is. I pasted the code over an old script I had, and it may have had the sh and I must have retained that.

Sorry. Carry on people :-)
