foreach loop using a "*" for args
have a script that copies a file to a bunch of hosts. works great with a single file. How do I make it copy all files in a source directory? or a *txt pattern, or anything using a * ???
name of script: cp2all
#!/bin/csh
foreach host ( host1 host2 host3 host4 host5 host6 host7)
rcp $argv[1] $host\:$argv[2]
end
i usually run the script to copy a single file like this
./cp2all test1.txt /home/ajp
this will copy test1.txt to /home/ajp on all the hosts listed in foreach.
I want to copy all files in a directory, but using * doesnt seem to work. How would I do this??
Thank you as always!!

Hi.
I have a copy-file script (and a move-file script) that I recently tried to make interactive. I tested the former on three files from a text list, and watched to see what would happen.

continue(1T) Tcl Built-In Commands continue(1T)
__________________________________________________________________________________________________________________________________________________
NAME
continue - Skip to the next iteration of a loop
SYNOPSIS
continue
_________________________________________________________________
DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code,
which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop
command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as
the catch command and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 10 except 5:
for {set x 0} {$x<10} {incr x} {
if {$x == 5} {
continue
}
puts "x is $x"
}
