UNIX for Dummies Questions & Answers

Basically i have done created the script below, and it functions ok, it prints the access rights the user has. But i need it to print the group permissions, and other permissions, it would also be helpful if i could print the permissions in numeric form aswell, if it is possible. I have looked in a few books but they were no help.


This is my script so far.... (This is a shortened version, i have simplified it)

Code:

Print -n "Enter a file/directory name"
read name
if [ -r $name ]
             then echo "This is file/directory is readable"
fi
if [ -w $name ]
             then echo "This is file/directory is writable"
fi
if [ -x $name ]
             then echo "This file/directory is executable"
fi
print "End"

Can ne1 help??

added code tags for readability --oombera

Let's use printf,

Code:

#!/bin/sh

 

printf "Enter a file/directory name\n"

read name

if [ -r $name ]

then echo "This is file/directory is readable"

fi

if [ -w $name ]

then echo "This is file/directory is writable"

fi

if [ -x $name ]

then echo "This file/directory is executable"

fi

printf "End\n"

Please post to tell me if this is possible or not? Because I have been waitin but dont look like anyone knows - which I doubt, I would have thought someone knows, guessing its not possible?????????

ADMINISTRATORS NOTE: THE TONE OF THIS POST IS AGAINST FORUM RULES. POSTER DANGEROUSLY CLOSE TO "READ ONLY" STATUS.... BE CAREFUL AND POLITE, PATIENT, OK Makaveli.2003 ?

Now now now, taunting people by saying that it can't be done in a Unix forum is silly, because you can do just about anything...
For example, try :
ls -ld /tmp | cut -c2-4

That will show you the permissions that the owner has on the /tmp directory (you should see rwx)

Now, if you read the man pages to see what the "-d" option to ls does, you know why you have to use it on directories - also, RTM on cut.

getacl should help you a little with this. See the man pages on the same.

Thanks to negative for his contribution though (No offence intended!)

Thanx LivinFree - that was great, but this is what I need help with:


1) Need to be able to print "group permissions" e.g if -rwxr-x--x
need to print "r-x"or whatever it is for that file/directory


2) Need to be able to print "other permissions" e.g. if -rwxr-x--x
need to print "--x" or whatever it is for that file/directory


3) Need to print the permissions numberically e.g. 700


I looked on man pages but they werent much help

Please help

Sorry, but I just been experimenting and thanx to LivinFree worked it out, but I still need a little help. This is wat ive worked out:

1) Need to be able to print "group permissions" e.g if -rwxr-x--x
need to print "r-x"or whatever it is for that file/directory

This is what i did: ls -ld filename | cut c5-7 (is this right)


2) Need to be able to print "other permissions" e.g. if -rwxr-x--x
need to print "--x" or whatever it is for that file/directory

This is what I did: ls -ld filname | cut c8-11 (is this right)


But I still need help with :

3) Need to print the permissions numberically e.g. 700
