You can also save yourself repeated calls to basename by using

for f in *eps; do
    convert ${f%.eps}.jpg
done

Look under parameter expansion in the manpage for sh(1) (or bash(1) if you 
have bash installed). As far as I can tell csh/tcsh doesn't support this 
useful feature.

Essentially, a Bourne-type shell with parameter expansion expands 
${variable#prefix} or ${variable%suffix} to $variable with the prefix or 
suffix, respectively, removed.
