I am trying to strip the suffix 'jpg' from a list of images. I keep
getting this error.

../writeimage: line 23: and this is what you catch.jpg: command not found
../writeimage: line 23: dave-damon-2006-3.jpg: command not found
../writeimage: line 23: Double exposure.jpg: command not found

Here is a snippet containing the error producing code.

for filename in *.jpg; ##list images in directory

do
if [ -f "$filename" ]
then

CAPTION=basename "$filename" .jpg

imageline="
<td align=\"center\"> <p style=\"margin-top: 0; margin-bottom: 0\"> <img
border=\"0\" src=\"$filename\"></a></p> <p style=\"margin-top: 0;
margin-bottom: 0\">"$CAPTION"</p> </td>"

This is a maintance tool for me. I run it on my debian based machine.

TIA
Dave

CAPTION=$( basename "$filename" .jpg )

or using shell builtins instead of costly external processes...

CAPTION=${filename%.jpg}

Worked like a charm. Thanks.
Where would I go to read/learn about some of this stuff. A google search
did not turn up any interesting leads.
Is there a better place than 'info coreutilities'? Does this cover builtins?

Thanks again.
Dave

The builtins depend on the used shell, for Kornshell for example you can
find the information in the manpage online
http://www.cs.princeton.edu/~jlk/kor...doc/man93.html
or for bash with man bash. Though careful about portability; even most
modern shells have a large common subset you may occasionally want
to restrict to the POSIX subset. (The above ${...%...} is POSIX.) Surely
the man pages are a good source to get an overview of the shell features.
