src, Bfn – find source code for executable|
src [ –n ] [ –s symbol ] file ... |
Src examines the named files to find the corresponding source
code, which is then sent to the editor using B (see sam(1)). If
file is an rc(1) script, the source is the file itself. If file
is an executable, the source is defined to be the single file
containing the definition of main and src will point the editor
at the line that
begins the definition. Src uses db(1) to extract the symbol table
information that identifies the source. |
Src looks for each file in the current directory, in /bin, and in the subdirectories of /bin, in that order.
The –n flag causes src to print the file name but not send it to the editor. The –s flag identifies a symbol other than main to locate.
Bfn finds the definition of all C functions named fn by searching
the .c files in the current directory. It prints the file name
and line number of each match found and submits the match to the
plumber(4) if it is unique. Fn can be a regexp(6).
Find the source to the main routine in /bin/ed:|
db(1), plumb(1), sam(1).|
Bfn requires the source code to follow style(6).|
