The following script checks whether the filename is correct then the script proceeds to check whether you have read,write and execute permisiions to the file and displays an approriate message.
echo "enter any filename \c"
if[!-z "$fname"] then
if [-r $fname -a -w $fname -a -x $fname]
echo you have read,wirte and execute permisions to $fname
echo read,write and execute permisions denied
echo improper filename
when i run this script and give the filename 'test' it is showing the following error.
|s23:line 3: if[!-z test]: command not found|
s23:line 4: if [-r test -a -w $fname -a -x test] : command not found
s23:line 5:syntax error near unexpected token 'then'
i have seen this program in a shell scripting book and tried it but it has shown the above said error. '-z ' returbs true if the lenght of the string is zero. what would be the equivalent command in Redhat linux. I am using Redhat llinux 9 version.
