I can see them using ls -la. Note: This script is working perfectly fine on RH4. I got new fresh RH6 machine on which I am trying to run my scripts. My abc.sh script as mentioned below . fox_comm_server_details.sh . fox_comm_topic_names.sh . fox_comm_sh_tools.sh refers to other script (.sh) files.

If I update the abc.sh as below... . ./fox_comm_server_details.sh . ./fox_comm_topic_names.sh . ./fox_comm_sh_tools.sh This time it is not complaining about missing files but some different error as mentioned below... read_fox_comm_servers_list[134]: read_fox_comm_servers_list_defaults[37]: local: not found [No such file or directory] read_fox_comm_servers_list and read_fox_comm_servers_list_defaults are functions that are defined in fox_comm_sh_tools.sh as follows... function read_fox_comm_servers_list { read_fox_comm_servers_list_defaults read_fox_comm_servers_list_overrides } function read_fox_comm_servers_list_defaults { local tempfile=/tmp/read_fox_comm_servers_list_defaults.$$ } and getting above mentioned error. shell-script redhat-enterp
