Unexpected command/filename substitution ( caused by alias?)
Hi:

there is a shell script, with the name "foo", located in a bin directory. in the same time, there is an alias "foo='/path/bin/foo' ", just for convenience.

in my home directory, there is a different script with name "foo" too. (a modified version.)

while in my home directory, when I do:

>$ cat foo

my local "foo" is displayed, as expected.

but if I do:
>$ source foo,

the common "/path/bin/foo" gets picked up, not my local one, as if the alias "foo" kicks in and substitutes the common "foo" for my local one.

to source my local "foo", I have to explicitly say:

>$ source ./foo

what I don't get is, the "foo" is the filename argument for both "cat" and "source" commands, but why the "foo" alias seemingly kicks in in "source" command, not the "cat" command.

Could any one shed some light on this?

Thanks.

NB Phil

dvired(1)                                                              teTeX                                                             dvired(1)

NAME

       dvired - print dvi-files

SYNOPSIS

       dvired [ options ] file

DESCRIPTION

       dvired behaves like dvips, except for the fact that two logical pages are put onto each physical sheet of paper.

       For options, see dvips(1).  This program only interprets the following options:

       -o file - redirect output into file.

       -P printer - direct output to printer.

       -f - direct output to stdout.

       Any other option is passed directly to dvips.

EXAMPLES

       It is assumed that the PRINTER-variable is set.

       dvired -Plw foo - send output to printer lw.
       dvired -o foo.ps foo - send output to file foo.ps.
       dvired -pp4-7 foo - send 4 pages (reduced onto 2 sheets) of foo to the printer.
       dvired foo -f | ghostview - - preview output with ghostview.

SEE ALSO

       dvips(1)

BUGS

       dvired is fixed on A4 paper size. If you want to use it with other paper, you have to change the settings within the source.
