SRC(1) SRC(1)
NAME
src, Bfn - find source code for executable
SYNOPSIS
src [ -n ] [ -s symbol ] file ...
Bfn fn
DESCRIPTION
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 defini-
tion. Src uses db(1) to extract the symbol table informa-
tion 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 sub-
mits the match to the plumber(4) if it is unique. Fn can be
a regexp(6).
EXAMPLES
Find the source to the main routine in /bin/ed:
src ed
Find the source for strcmp:
src -s strcmp rc
SOURCE
/rc/bin/src
SEE ALSO
db(1), plumb(1), sam(1).
BUGS
Bfn requires the source code to follow style(6).
