sed: command garbled - when executed with $variables
I have got a file job_tree.lst , which contains 1 line as below

$ cat job_tree.lst
ABC_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0

I want to get a child job string 3 characters offset from the parent job string (i.e. ABC_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0 available in job_tree.lst)
The command I am using in shell script to carry out the above task is as below

grep $parent job_tree.lst | tail -1 |sed -e 's*'${parent_job_rep}'*'' '${child_job_rep}'*'

but it's producing an error “SED command: Command Garbled error”

Pl see the test below what I have done in the command prompt

$ cat job_tree.lst
ABC_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0

$ echo $parent
ABC_D_EQ_XXXXX_YYYY_PRD_UX

$ echo $child_job_rep
XYZ_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0

$ echo $parent_job_rep
ABC_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0

$ grep $parent job_tree.lst | tail -1 |sed -e 's*'${parent_job_rep}'*'' '${child_job_rep}'*'
sed: command garbled: s*ABC_D_EQ_XXXXX_YYYY_PRD_UX

But when I give literals in place of substitution variables , it's working see below

$ grep $parent job_tree.lst | tail -1 |sed -e 's*ABC_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0* XYZ_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0*'
XYZ_D_EQ_XXXXX_YYYY_PRD_UX 05/08/2009 05:47 05/08/2009 05:50 IN 13412850/0

Can the experts help?

Thanks

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).
