The primary token delimiter in POSIX Shell is space. Hence, the
following line:
if [ -f /data/newdatabase.db];
Is understood as: “check if the file ‘/data/newdatabase.db]’
exists” (note the closing bracket), and it certainly lacks a
closing bracket for the ‘test’ (AKA ‘[’) command.
The solution would be as follows:
- if [ -f /data/newdatabase.db];
+ if [ -f /data/newdatabase.db ];
OTOH, the when the ‘test’ form of the command is used, closing
bracket is not necessary, thus:
if test -f /data/newdatabase.db ;
Please also consider joining the news:comp.unix.shell newsgroup
(e. g., on Aioe, nntp://aioe.org/comp.unix.shell/), as there're
quite a few folks familiar with the arcane art of Unix Shell
programming. (AFAIK, Thunderbird has the support for the
Internet News service.)
