### mk_fol_names.install - make links for mk_fol_names script
### Usage: mk_fol_names.install [-v]
##
##  Makes hard links from $progname (mk_fol_names) file to
##  each program listed in $table.  NOTE: REMOVES any existing
##  file or link with the same name!.. you may want to modify
##  to use "mv ... /tmp", instead of "rm -f ...", for safety.
##
##  -v switch turns on verbose mode.
##
##  NOTE: Read the whole script before you use it!  Modify if needed.

# That table would handle commands amb, amba, ambr, fmb, fmba, fmbr.

# Note: csh_folders and sh_folders are hardcoded. 
# Also, this sed script names link names starting with "a" and "f".
# If you changed mk_fol_names to use other letters, fix "s" commands in script:
links="csh_folders sh_folders

s/^/a/p
g
s/^/f/p' $table`"

# NOTE: You may want to change this command to preserve old files:
# /bin/rm -f $links 2>&1
/bin/mv -f $links /tmp >/dev/null 2>&1
# temp -v $links
