creating array variable
Hi all,
i am quite fimiliar with shell scripting but i wouldn't regard myself as a semi professional at it.
I am trying to create an array variable to read in 4 lines from a file using head and tail command in a pipeline and store each line into each array. I have done the scripting in unix but for some reason i keep getting syntax errors during runtime saying 'mon=' unexpected.
for the moment i am trying to create a simple script to store months Jan, Feb Mar Apr into array mon but its not having it and i don't know why. i did google searches and i tried a number of the examples i found but none work
i tried to use declare -a mon but it says "declare: not found" - is it something to do with the first line - #!/bin/bash?
#!/bin/bash
mon=( Jan Feb Mar Apr )
echo $mon
can someone please throw some light onto this becuase its doing my head in.
thanks in advance
Mani

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
