Re: behaviour of "for (( exp1; exp2; exp3 )); do COMMANDS; done"


Peter,

Make sure your scripts explicitly state /bin/bash as their shell. The default shell (i.e. /bin/sh) under Cygwin is ash, not BASH. It produces the diagnostic you mention when given that command.

When using a line like "for (( i=1 ; i<=5 ; i+=1 )); do echo $i; done" in a bash script one expects to get a list of figures ranging from 1 to 5 right?
I've never had problems with such constructs on my Linux machine but when doing this in a cygwin bash shell, then it works fine when typed in at the command line but fails with a syntax error "Bad for loop variable" when executed in a script.


Where did I go wrong? Ideas anybody?

Thanks in advance,

Peter.
