I was thinking something like this but it always gets rid of the file location.
grep -roh base. | wc -l
find . -type f -exec grep -o base {} \; | wc -l
Would this be a job for awk? Would I need to store the file locations in an array? (3 Replies)

TIME(3) BSD Library Functions Manual TIME(3)
NAME
time -- get time of day
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <time.h>
time_t
time(time_t *tloc);
DESCRIPTION
The time() function returns the value of time in seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time.
A copy of the time value may be saved to the area indicated by the pointer tloc. If tloc is a NULL pointer, no value is stored.
Upon successful completion, time() returns the value of time. Otherwise a value of ((time_t) -1) is returned and the global variable errno
is set to indicate the error.
ERRORS
No errors are defined.
SEE ALSO
gettimeofday(2), ctime(3)
STANDARDS
The time() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
HISTORY
A time() function appeared in Version 2 AT&T UNIX. It returned a 32-bit value measuring sixtieths of a second, leading to rollover every
2.26 years. In Version 6 AT&T UNIX, the precision of time() was changed to seconds, allowing 135.6 years between rollovers.
In NetBSD 6.0 the time_t type was changed to be 64 bits wide, including on 32-bit machines, making rollover a concern for the far distant
future only. Note however that any code making the incorrect assumption that time_t is the same as long will fail on 32-bit machines in
2038.
