Either you do like spirtle said or you use a separate sed script to change every "/" in the $tab2 variable to a "\/" prior to using the variables content:

Code:
tab2="(print - "$tab2" | sed 's/\//\\\//g')"

I hope this helps.

HISTORY

       The GNU shtool subst command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 2001 for GNU shtool.  It was prompted
       by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.

SEE ALSO

       shtool(1), sed(1).
