Hi guys, I was given a script from my teacher to do make some changes. However, I have no knowledge of program C. I would appreciate if anyone are able to advice me what is the error on the scripts. The script is echo " select any option to execute:" echo " c or C: To connect Client to Server" echo " r or R: To make a read request" echo " s or S: I want to sort data" echo " g or G: Look for a certain word in a file" echo " e or E: quit" echo -n "Enter your option and press <Enter>:" set selection = `head -1` switch ("$selection") case [cC]: echo -n "enter server name" set servername = `head -1` find $servername breaksw case [rR]: cp echo -n "enter server file to read content" set serverfile = `head -1` breaksw case [sS]: sort echo -n "enter server file to sort" set serverfile1 = `head -1` breaksw case [qQ]: exit 0 breaksw default: case [qQ]: exit 0 breaksw default: echo " wrong option." exit 1 breaksw endsw exit 0 I have change the script to executable. When I run it, It shows darren@linux:~$ ./clientlooker1 select any option to execute: c or C: To connect Client to Server r or R: To make a read request s or S: I want to sort data g or G: Look for a certain word in a file e or E: quit Enter your option and press <Enter>:4 ./clientlooker1: line 10: syntax error near unexpected token `"$selection"' ./clientlooker1: line 10: ` switch ("$selection")' darren@linux:~$ If someone can advice me with this, that would be greatly appreciated. Many thanks, Darren
