Validating multiple file

rameshpaul_cog · 07-06-2012, 09:59 AM

Hi,

It may be simple ... but am not getting a break here...Any help would be really appreciated...

I want to validate couple of variables before i execute a command

Here is the scenario

Code:

count=' ${NAME_SRC_PATH} | grep "^${name}\/$" | wc -l`
if [ $count -eq 0 ];
then
        echo "Error Creating ${name} "
        exit 1
else
        echo "Name Created."
fi

Now i want to check some 5 more src_path .. how can i chk that... ?

Say like NAME_SRC_PATH1,NAME_SRC_PATH2.NAME_SRC_PATH3,NAME_SRC_PATH4,NAME_SRC_PATH5...

the paths are declared by me only ...and if the name exists in NAME_SRC_PATH3 .. it should return name exits is 3...likewise..for all...

i understand its simple... am totally blank now... any pointer would be helpful....

To check for blank variables, I usually do something simple like:

Code:

if [ x$VARIABLE == "x" ]; then
  echo blank
else
  echo not blank
fi

If you're looking to see if a directory exists then it's a bit different

Code:

if [ -d $DIRECTORY ]; then
  echo dir exists
fi
