UNIX for Dummies Questions & Answers

Hi,
OS - Unix, linux (all unix flavors)
My requirement. To check directory/file exists and then change the permission of the directories/files.

Iam trying to start with directory and here is my code in the file totalchange.sh (insideragain - is a directory, test1.txt - is a file under the directory insideragain)

totalchange.sh file

Code:

$1 = insideragain
if [ ! -d "$1" ]
    then
      chmod 550 test1.txt
fi

when i run it, i get the following error message

Code:

rt-opuX4:$ totalchange.sh
totalchange.sh[2]: =:  not found

where am i wrong?

Next i want to check if file exists, so

totalchange1.sh
$1 = insideragain
$2 = test1.txt
if [ ! -d "$1" ]
if [ ! -f "$2"]
then
chmod 550 $2
fi
elsif
echo "directory not find"
fi

Can anyone point to right direction for both these files totalchange.sh and totalchange1.sh?

thanks

Here i did not get you why are you using

Code:

totalchange.sh file

are you parsing any argument to totalchange.sh script?
if not then..

You can try like this..


cat totalchange.sh

Code:

var="insideragain"
if [ ! -d $var ]
then
chmod 550 test1.txt
fi

cat totalchange1.sh

Code:

var="insideragain"
var1="test1.txt"
if [ ! -d "$1" ]
then
if [ ! -f "$2"]
then
chmod 550 $2
fi
echo "directory not find" 
fi

Hope this helps your need..

THanks
SHa

Thanks for your post.
To answer your question, Yes iam not passing any parameters.
Iam using the var as you mentioned.

I made some modifications and its working fine, perfect.
(The script i changed -

Code:

var1="insideragain"
var2="inside2.html"
if [ ! -d $var1 ];
then
echo $var1
echo "Directory not found"
  exit 1
  else
    if [ ! -f $var2 ]
       then
       chmod 444 $var1/inside2.html
    fi
#else
#echo "Directory not found"
fi)

One more question:
Is there any way to loop it. i mean

if <condition true>
then <do something>
elsif goto nextstep

In windows batch script i can use (In the below case if it does not satisfy i go to "nextstep" and it works from there)

if not <condition true> goto nextstep
then <do something>
endif
:nextstep
<whatever needs to be done here>

Thanks for your valuable input. It worked. I appreciate too.
