POBASH Scripting assistance needed
text
Body
copied!<p>Well, I am currently a novice shell scripter. I have a basic knowledge of other programming languages such as Javascript for HTML, JScript, VB.NET, and C++. (C++ Not so much, just dipped my feet in the water for that). Most recently, my recent project has been attempting to learn as much as I can about Bash shell scripting. The current issue is understanding status error codes, as well as checking if certain parameters contain directories or if it exists at all. I am working from a book, with tutorials and review questions. Unfortunately there is no answer key, or even hints for that matter. </p> <ul> <li>Display an error message and exit with status 1 if no parameters are given</li> <li>Display an error message and exit with status 2 if source is not a directory</li> <li>Display an error message and exit with status 3 if destination does not exist or is not a directory</li> </ul> <p>The above is what I must do, so far the first one I believe I have done correctly, if not please, correct me, or guide me in the proper direction. As I learn best when samples are given, I thought I would ask for assistance.</p> <pre><code>if [ $? ]; then echo "You must supply at least one parameter" exit 1 fi #The above is the part I am pretty sure is correct. if [ $? -d $directory "$1" ]; then echo "$directory is not a directory" exit 2 fi #The above was self written. I am almost positive it is wrong. if [ $? -lt 2 ]; then set "$1" .pwd fi #the above was given to me from the book as a reference point to start (tutorial) </code></pre>
