Full Discussion: Initialize aliases during shell script execution

There seems to be a lot of disagreement on this, but as I understand it, aliases are for interactive use -- not generally for scripted use. For scripts, you'd use functions. It's possible to enable aliases in noninteractive scripts in some shells, but if you feel the need to do so, there may be design problems underlying your work.

Your "here document" in particular has me worried that you are expecting alias substitutions to happen in a place they never will, however -- inside things like here-documents, dynamically generated code, etc. It'd take an eval to shoehorn them in there, which is a class-9 bad idea for a variety of reasons. Could you tell me exactly how you are trying to use these aliases?

ali

ali(1)							      General Commands Manual							    ali(1)

NAME

       ali - list mail aliases (only available within the message handling system, mh)

SYNOPSIS

       ali [-alias aliasfile] [-help] [-[no]list] [-[no]normalize] [-user useraddr] [-nouser] [aliases...]

OPTIONS

       Specifies  the alias file to be consulted by ali.  You can specify more than one alias file, but each aliasfile must be preceded by -alias.
       In addition to any alias files that you specify, ali consults the system alias file /usr/lib/mh/MailAliases.

	      You can set up an entry in your so that ali automatically consults an alias file. To do this, add the Aliasfile entry to	your  pro-
	      file. See mh_profile(4) for more information.  Prints a list of the valid options to this command.  Prints the addresses on separate
	      lines. If you do not specify the -list option, the addresses are separated by commas and	printed  on  as  few  lines  as  possible.
	      Instructs  ali  to try to track down the official hostname of the address. This can be suppressed by using -nonormalize. The default
	      is -nonormalize.	Displays all the aliases that contain a specific name. Instead of listing the  addresses  that	each  given  alias
	      expands  to,  ali lists the aliases that expand to include each given address. You must specify the complete user name that you have
	      used in your alias file.

       The defaults for this command are:

       -alias /usr/lib/mh/MailAliases -nolist -nonormalize -nouser

DESCRIPTION

       The ali command searches the specified mail alias files for each of the given aliases. It creates a list of addresses  for  those  aliases,
       and displays that list on the screen.

PROFILE COMPONENTS

       Location of your mail directory.  Location of your personal alias file.

EXAMPLES

       The  following  example	shows  how  the  -user option can be used to list all the aliases containing the address Parker@Venus: % ali -user
       Parker@Venus Parker@Venus: Group, Reviewers, Badminton

FILES

       The user profile.  The system alias file.  The system password file.  The system group file.
