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.
#ss23 #usage ss23 echo "enter any filename \c" read fname if[!-z "$fname"] then if [-r $fname -a -w $fname -a -x $fname] then echo you have read,wirte and execute permisions to $fname else echo read,write and execute permisions denied fi else echo improper filename fi
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 ' returns true if the lenght of the string is zero(this could be in Unix). what would be the equivalent command in Redhat linux. I am using Redhat llinux 9 version.
