NAME

src  − find source code for executable

SYNOPSIS

­src [ ­-n ] [ ­-s ­symbol ] ­file ­... 

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 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. 

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
