Is this a script written by you ? The simplest way is to insert
a read statement at the level that you want to stop and examine;
so that it waits for a [Return] before going to the next step:
e.g. ls -al /bla/bla*
read
file /bla/bla.1

Segmentation fault is never caused by your script. It would be
because of library incompatibilities (usually) in the binary
itself. Run the binary (program) directly outside the script to
find out ... It is unlikely that your problem will be sorted out
by stepping through your script even if you run under the
verbose execute mode (-vx) command line option.
Do a ldd of the binary and check for libs needed.
