I am trying to write a simple C program so that I can learn
how to use C. I have no trouble writing the program and creating
the ex01-1.c file. I can compile the ex01-1.c file and obtain
the ex01-1.0 file and then link the pieces to obtain the
executable file ex01-1. When I run ex01-1 file I get the
permission denied and do not know how to get rid of it. As shown
below I have adjusted all the permissions that I can think of
to no avail. Any help will be appreciated.
 
clay@linux:/data4/C-Prog/Horton/les01 > ls -l
-rwxrwxr-x    1 clay     users        4838 Jul 13 06:39 ex01-1
-rw-r--r--    1 clay     users         127 Jul 13 06:36 ex01-1.c
-rw-r--r--    1 clay     users         912 Jul 13 06:37 ex01-1.o
 
clay@linux:/data4/C-Prog/Horton/les01 > ex01-1
bash: ./ex01-1: Permission denied
 
clay@linux:~ > ls -l /
drwxrwxr-x    4 root     users        4096 Jul 13 06:30 data4

/dev/hdc2       /data4  auto    noauto,user 0 0
 
clay@linux:~ > ls -l /dev/hdc2
brw-rw----    1 root     users     22,   2 Jan 19 01:36 /dev/hdc
