Hi, I need to replace a character between two numbers (specifically a - to a _). The problem is that they can be *any* numbers. So, I need a one liner to turn a file like this:
1-2
3-4
55-66
4323-12312893
into the following
1_2
3_4
55_66
4323_12312893
Any help would be appreciated! (5 Replies)

getservbyport
GETSERVENT(3N)GETSERVENT(3N)NAME
getservent, getservbyport, getservbyname, setservent, endservent - get service entry
SYNOPSIS
#include <netdb.h>
struct servent *getservent()
struct servent *getservbyname(name, proto)
char *name, *proto;
struct servent *getservbyport(port, proto)
int port; char *proto;
setservent(stayopen)
int stayopen
endservent()
DESCRIPTION
Getservent, getservbyname, and getservbyport each return a pointer to an object with the following structure containing the broken-out
fields of a line in the network services data base, /etc/services.
struct servent {
char *s_name; /* official name of service */
char **s_aliases; /* alias list */
int s_port; /* port service resides at */
char *s_proto; /* protocol to use */
};
The members of this structure are:
s_name The official name of the service.
s_aliases A zero terminated list of alternate names for the service.
s_port The port number at which the service resides. Port numbers are returned in network byte order.
s_proto The name of the protocol to use when contacting the service.
Getservent reads the next line of the file, opening the file if necessary.
Setservent opens and rewinds the file. If the stayopen flag is non-zero, the net data base will not be closed after each call to get-
servbyname or .IR getservbyport .
Endservent closes the file.
Getservbyname and getservbyport sequentially search from the beginning of the file until a matching protocol name or port number is found,
or until EOF is encountered. If a protocol name is also supplied (non-NULL), searches must also match the protocol.
FILES
/etc/services
SEE ALSO getprotoent(3N), services(5)DIAGNOSTICS
Null pointer(0) returned on EOF or error.
BUGS
All information is contained in a static area so it must be copied if it is to be saved. Expecting port numbers to fit in a 32 bit quan-
tity is probably naive.
