EXAMPLES

To read a line from the keyboard and append it to a file, enter:

echo ’Enter comments for the log:’
echo ’: \c’
line >>log

This shell procedure displays the message:

Enter comments for the log:

It then reads a line of text from the keyboard and adds it to the end of the file log.  The echo ’: \c’ command displays a : (colon) prompt.  See the echo command for information about the \c escape sequence.
