Edit File: pamfixtrunc
#!/bin/sh ############################################################################## # This is essentially a Perl program. We exec the Perl interpreter specifying # this same file as the Perl program and use the -x option to cause the Perl # interpreter to skip down to the Perl code. The reason we do this instead of # just making /usr/bin/perl the script interpreter (instead of /bin/sh) is # that the user may have multiple Perl interpreters and the one he wants to # use is properly located in the PATH. The user's choice of Perl interpreter # may be crucial, such as when the user also has a PERL5LIB environment # variable and it selects modules that work with only a certain main # interpreter program. # # An alternative some people use is to have /usr/bin/env as the script # interpreter. We don't do that because we think the existence and # compatibility of /bin/sh is more reliable. # # Note that we aren't concerned about efficiency because the user who needs # high efficiency can use directly the programs that this program invokes. # ############################################################################## exec perl -w -x -S -- "$0" "$@" #!/usr/bin/perl ############################################################################## # This is nothing but a compatibility interface for Pamfixtrunc. # An old program coded to call Pamfixtrunc will continue working because # this interface exists.
