[9fans] broken cmd

[Donald Brownlee <brownlee@acm.org>]

Hi,

In the initial Release 3 (summer of 2000?) the 'src'
command worked for both shell scripts and '8.out' files.
In a distribution that was downloaded from the Plan 9
web site, yesterday, the 'src' command no longer works
for '8.out' files.

I got it to work by modifying /rc/bin/src:

  term% diff /rc/bin/src.original /rc/bin/src
  7c7
  <   echo $sym | db $1 | sed '1d;/symbol not found/d;s/.*\(\) //'
  ---
  >   echo $sym | db $1 | sed '1,2d;/symbol not found/d;s/.*\(\) //'

There may have been an extra 'dprint' placed in /sys/src/cmd/db/main.c,
which could explain why two lines instead of one must be deleted from
the output of 'db'.

Regards,
