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

set
set(n) Tcl Built-In Commands set(n)
__________________________________________________________________________________________________________________________________________________
NAME
set - Read and write variables
SYNOPSIS
set varName ?value?
_________________________________________________________________
DESCRIPTION
Returns the value of variable varName. If value is specified, then set the value of varName to value, creating a new variable if one
doesn't already exist, and return its value. If varName contains an open parenthesis and ends with a close parenthesis, then it refers to
an array element: the characters before the first open parenthesis are the name of the array, and the characters between the parentheses
are the index within the array. Otherwise varName refers to a scalar variable. Normally, varName is unqualified (does not include the
names of any containing namespaces), and the variable of that name in the current namespace is read or written. If varName includes names-
pace qualifiers (in the array name if it refers to an array element), the variable in the specified namespace is read or written.
If no procedure is active, then varName refers to a namespace variable (global variable if the current namespace is the global namespace).
If a procedure is active, then varName refers to a parameter or local variable of the procedure unless the global command was invoked to
declare varName to be global, or unless a variable command was invoked to declare varName to be a namespace variable.
