Ok, you'll have to to this on a per-editor basis, alas.
If joe has a +nnn option, try:
# or egrep, depend what flavour regexp you're offering
n=`grep -n "$pattern"<"$file" | sed 's/:.*//'`
joe "+$n" "$file"
You'll need to work out variations for other editors, alas.

Hello Mr. Cameron and James,
thank You for these suggestion. I didn't want just jump to line with
searched text, because lines in edited files are long - sometimes up to
300-400 chars (sorry, I'm not author of them :). Then, I want jump right
on the edited text. At present it appears as simple editors cannot do
this. I have working solution in vim:
$ vim -i NONE -S <(echo -e "/SrchdPattern...\\zs/\nnormal n") EditedFile
("...\\zs/\nnormal n" construct is there because I want edit text 3 chars
after searching pattern).
It seems as my users will must know several vim commands. Or they will
had lesser comfort with some simpler editor.
Regards, Franta Hanzlik
