using brackets in scripts

using brackets in scripts

[Pol]

While the command 
ls -l save/*(.)  

returns a list of files, as expected, entering the same command in a shell
script does not work, returning:
   
     Syntax error: "(" unexpected

Any ideas?

Thank you

You're using zsh's glob-qualifiers in a script interpreted by another
shell. These qualifiers are zsh specific.

Your script is likely being run by different shell (bash or whatever). I 
was not able to achieve this effect by (un-)setting zsh options.

My script starts with 
  #!/bin/zsh

but then commands are preceded by  'sudo' 

Same result if commands in script are not preceded  by 'sudo', but the
script itself is launched by 'sudo' . 

anyway, no errors when the command is entered through the interactive shell
  sudo ls -l save/*(.) 

Any ideas?

=================

within the script, run the commands "zmodload", "setopt" and "autoload -U 
zargs", and see if you get output that makes sense in a zsh environment. 
if not, the commands within your script are not being executed by zsh.

also, on your command line, check the path to zsh:
 	ls -lh =zsh

it might be in /usr/local/bin/zsh, which might cause the script to default 
to a bourne shell, and the zsh glob tricks will fail.

if the commands are preceded by sudo, try:
 	sudo zsh -c ls -l save/*(.)

or, try setting "SHELL=zsh" towards the top of the script, before invoking 
sudo.

Problem solved: i have moved the line
#!/bin/zsh
to the top of the script (a few comment lines were on top, at my first
attempt)

Thank you, anyway

Ah nostalgia that was one of first mistakes in scripting (not the last one  
of course!)
