Read one line from stdin

zhshqzyc · #1 (**permalink**) 10-07-2007

Hello,

I am Read one line from stdin

stdin is the keyboard unless input redirection used
Read one line from stdin, store line in a variable
read variable_name
Ask the user if he wants to exit the script
Store the following in a file named read.sh and execute it

Code:

#!/bin/sh
# Shows how to read a line from stdin
echo "Would you like to exit this script now?"
read answer
if [ "$answer" = y ]
then
echo "Exiting..."
exit 0
fi

Here is the snapshort

Code:

Owner@YOUR-787F71A704 ~
$ sh read.sh
Would you like to exit this script now?
y
read.sh: line 5: [y: command not found

Please advise!
Thanks

from the error it sounds like you actually missed the space between [ and ".

Note, [ is often a link to test, it is useful to know that [ is just a program.
