Hey All,
I want to get the access time of files in a directory.
I used ls -lu on a directory and picked a file that had the access time of Mar 1 and used cat to get the contents of the file. Then I used the ls -lu again and the access time changed on that file. Perfect !!
Now if I cat a... (10 Replies)

utime
utime(2) System Calls utime(2)NAME
utime - set file access and modification times
SYNOPSIS
#include <sys/types.h>
#include <utime.h>
int utime(const char *path, const struct utimbuf *times);
DESCRIPTION
The utime() function sets the access and modification times of the file pointed to by path, and causes the time of the last file status
change (st_ctime) to be updated.
If times is NULL, the access and modification times of the file are set to the current time. A process must be the owner of the file or
have write permission to use utime() in this manner.
If times is not NULL, times is interpreted as a pointer to a utimbuf structure (defined in <utime.h>) and the access and modification times
are set to the values contained in the designated structure. Only the owner of the file or a process that has the {PRIV_FILE_OWNER} privi-
lege asserted in its effective set can use utime() in this manner.
The utimbuf structure contains the following members:
time_t actime; /* access time */
time_t modtime; /* modification time */
The times contained in the members of the utimbuf structure are measured in seconds since 00:00:00 UTC, January 1, 1970.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The utime() function will fail if:
EACCES Search permission is denied by a component of the path prefix.
EACCES The process does not have appropriate privileges and is not the owner of the file, write permission is denied for the file,
and times is NULL.
EFAULT The path argument points to an illegal address.
EINTR A signal was caught during the execution of the utime() function.
EIO An I/O error occurred while reading from or writing to the file system.
ELOOP Too many symbolic links were encountered in translating path.
ENAMETOOLONG The length of the path argument exceeds PATH_MAX, or the length of a path component exceeds NAME_MAX while _POSIX_NO_TRUNC
is in effect.
ENOENT The named file does not exist or is a null pathname.
ENOLINK The path argument points to a remote machine and the link to that machine is no longer active.
ENOTDIR A component of the path prefix is not a directory.
EPERM The effective user of the calling process is not the owner of the file, {PRIV_FILE_OWNER} is not asserted in the effective
set of the calling process, and times is not NULL.
EROFS The file system containing the file is mounted read-only.
