Hi
Is there a way to cut the last two characters off a word or number given that this word or number can be of varying length?
I have tried something like
TEST=`echo $OLD | cut -c 1-5`
where $OLD is a variable containing a number like 1234567 which gives a result of 12345. This is fine... (4 Replies)

GETLASTLOGX(3) BSD Library Functions Manual GETLASTLOGX(3)NAME
getlastlogx, getutmp, getutmpx, updlastlogx, updwtmpx, utmpxname -- user accounting database functions
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <utmpx.h>
struct lastlogx *
getlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);
void
getutmp(const struct utmpx *ux, struct utmp *u);
void
getutmpx(const struct utmp *u, struct utmpx *ux);
int
updlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);
int
updwtmpx(const char *file, const struct utmpx *utx);
int
utmpxname(const char *fname);
DESCRIPTION
The getlastlogx() function looks up the entry for the user with user id uid in the lastlogx(5) file given by fname and returns it in ll. If
the provided ll is NULL, the necessary space will be allocated by getlastlogx() and should be free()d by the caller.
The getutmp() function fills out the entries in the struct utmp u with the data provided in the struct utmpx ux. getutmpx() does the oppo-
site, filling out the entries in the struct utmpx ux with the data provided in the struct utmp u, and initializing all the unknown fields to
0. The sole exception is the ut_type field, which will be initialized to USER_PROCESS.
The updlastlogx() function tries to update the information for the user with the user id uid in the lastlogx(5) file given by fname with the
data supplied in ll. A struct lastlogx is defined like this:
struct lastlogx {
struct timeval ll_tv; /* time entry was created */
char ll_line[_UTX_LINESIZE]; /* tty name */
char ll_host[_UTX_HOSTSIZE]; /* host name */
struct sockaddr_storage ll_ss; /* address where entry was made from */
};
All the fields should be filled out by the caller.
The updwtmpx() function updates the wtmpx(5) file file with the utmpx(5) entry utx.
The utmpxname() function sets the default utmpx(5) database file name to fname.
RETURN VALUES
getlastlogx() returns the found entry on success, or NULL if it could not open the database, could not find an entry matching uid in there,
or could not allocate the necessary space (in case ll was NULL).
utmpxname() returns 1 on success, or 0 if the supplied file name was too long or did not end with 'x'.
updlastlogx() and updwtmpx() return 0 on success, or -1 in case the database or file respectively could not be opened or the data not written
into it.
SEE ALSO endutxent(3), loginx(3), utmpx(5)HISTORY
The functions getutmp(), getutmpx(), updwtmpx(), and utmpxname() first appeared in Solaris. getlastlogx and updlastlogx first appeared in
NetBSD 2.0.
