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

prof

PROF(1) 						      General Commands Manual							   PROF(1)

NAME

       prof - display profile data

SYNOPSIS

       prof [ -v ] [ -a ] [ -l ] [ -low [ -high ] ] [ file ]

DESCRIPTION

       Prof interprets the file mon.out produced by the monitor subroutine.  Under default modes, the symbol table in the named object file (a.out
       default) is read and correlated with the mon.out profile file.  For each external symbol, the percentage of time  spent	executing  between
       that symbol and the next is printed (in decreasing order), together with the number of times that routine was called and the number of mil-
       liseconds per call.

       If the -a option is used, all symbols are reported rather than just external symbols.  If the -l option is used, the output  is	listed	by
       symbol value rather than decreasing percentage.

       If the -v option is used, all printing is suppressed and a graphic version of the profile is produced on the standard output for display by
       the plot(1) filters.  The numbers low and high, by default 0 and 100, cause a selected percentage of the profile to be plotted with accord-
       ingly higher resolution.

       In  order for the number of calls to a routine to be tallied, the -p option of cc must have been given when the file containing the routine
       was compiled.  This option also arranges for the mon.out file to be produced automatically.

FILES

       mon.out	for profile
       a.out	for namelist

SEE ALSO

       monitor(3), profil(2), cc(1), plot(1)

BUGS

       Beware of quantization errors.
