Since you are reading this book it can be assumed that you are going to be writing a good number of scripts. Here is another handy trick I learned over the years. When I need to create a new script, instead of doing it from scratch I use this simple command:
#!/bin/sh
#
# 1/26/2014
#
# create a command script
if [ $# -eq 0 ] ; then
echo "Usage: mkcmd command"
echo " Copies mkcmd.template to command and edits it with kw"
exit 255
fi
if [ -f $1 ] ; then
echo File already exists!
exit 2
fi
cp $BIN/mkcmd.template $1
kw $1
exit 0
And here is the contents of the $BIN/mkcmd.template file:
#!/bin/sh
#
# Date
#
if [ $# -eq 0 ] ; then
echo "Usage: "
echo " "
exit 255
fiBe sure that after you create the mkcmd.template file that you run chmod 755 on it. That way you do not have to remember to do it every time on your new commands. In fact, that was the main reason I wrote this script.
Feel free to modify this however you want, and of course change kw to vi or whatever editor you are using.
