Shell Script - Reminder Utility

Script : Reminder Utility

Script Name: remember.sh, remindme.sh

Script Function: The first script, remember , lets you easily save
your snippets of information into a single rememberfile in your home directory.
If invoked without any arguments, it reads standard input until the
end-of-file sequence (^D) is given by pressing CTRL-D. If invoked with arguments,
it just saves those arguments directly to the data file.
remindme, a companion shell script , either displays the contents of the whole rememberfile when no arguments are given or displays the results of searching through it using the arguments as a pattern.

Script Usage: ./remember.sh < arg >
                         ./remindme.sh < arg >

Code:

remeber.sh

#!/bin/bash
# remember--An easy command line-based reminder pad
rememberfile="$HOME/.remember"
if [ $# -eq 0 ] ; then
# Prompt the user for input and append whatever they write to
# the rememberfile.
        echo "Enter note, end with ^D: "
        cat - >> $rememberfile
else
# Append any arguments passed to the script on to the .remember file.
 echo "$@" >> $rememberfile
fi

exit 0

remindme.sh

#!/bin/bash

# remindme--Searches a data file for matching lines or, if no

# argument is specified, shows the entire contents of the data file

rememberfile="$HOME/.remember"

if [ ! -f $rememberfile ] ; then

        echo "$0: You don't seem to have a .remember file. " >&2

        echo "To remedy this, please use 'remember' to add reminders" >&2

        exit 1

fi

if [ $# -eq 0 ] ; then

        # Display the whole rememberfile when not given any search criteria.

        more $rememberfile

else

        # Otherwise, search through the file for the given terms, and display

        # the results neatly.

        grep -i -- "$@" $rememberfile | ${PAGER:-more}

fi

exit 0
