Scripting help

Carlo Henrico_1 — Mon, 09 Apr 2001 10:05:54 GMT

Firstly where can I get some guidelines for scripting?

Secondly, I need to test in one of my scripts whether one of the parameters entered ends with a ".h". Any ideas on how I go about this please?

Thanks

Carlo

If you are already familiar with the basics of scripting a good reference as always are the manpages of the various shells:

man sh
man sh-posix
man ksh
man csh

Otherwise get a text book for your preferred shell.
I always found the O'Reilly books quite worthwhile.

Here is a suggestion for testing for header filename suffixes passed as parameters to a script (though this is not particularly elegant and could be done better)

#!/bin/sh

for param in $*; do
if [ "${param#*.}" = "h" ]; then
# do something
fi
done

Hi Carlo!
echo |grep .h > /dev/null
if [ $? != 0 ]; then
or
if [ $? = 0 ]; then

example:
echo $2 |grep .h > /dev/null

good luck.

Carlo:

See these two threads for a sampling of suggestions for good references/guides to shell scripting:

Pedro

Thanks so far, this seems to work however, I presume $? is the return code from the last command?

Thanks

That's true...! Just to check if it went OK.
If the result is 0, then the argument has .h, if it's not then it hasn't.
