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(1) General Commands Manual PROF(1)
NAME
prof - display profile data
SYNOPSIS
prof [ -a ] [ -l ] [ -n ] [ -z ] [ -s ] [ -v [ -low [ -high ] ] ] [ a.out [ mon.out ... ] ]
DESCRIPTION
Prof interprets the file 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 profile file (mon.out default). 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 milliseconds per call. If more than one profile file is specified, the output represents the sum of the profiles.
In order for the number of calls to a routine to be tallied, the -p option of cc, f77 or pc must have been given when the file containing
the routine was compiled. This option also arranges for the profile file to be produced automatically.
Options are:
-a all symbols are reported rather than just external symbols.
-l the output is sorted by symbol value.
-n the output is sorted by number of calls
-s a summary profile file is produced in mon.sum. This is really only useful when more than one profile file is specified.
-v all printing is suppressed and a graphic version of the profile is produced on the standard output for display by the plot(1) fil-
ters. When plotting, the numbers low and high, by default 0 and 100, may be given to cause a selected percentage of the profile to
be plotted with accordingly higher resolution.
-z routines which have zero usage (as indicated by call counts and accumulated time) are nevertheless printed in the output.
FILES
mon.out for profile
a.out for namelist
mon.sum for summary profile
SEE ALSO
monitor(3), profil(2), cc(1), plot(1G)
BUGS
Beware of quantization errors.
Is confused by f77 which puts the entry points at the bottom of subroutines and functions.
