|
|
* HISTORY:
|
||
|
|
* 25-Jan-2000 a-anurag in the 'found' function changed the printf format of the year in the date from
|
||
|
|
* %d to %02d and did ptm->tm_year%100 to display the right year in 2 digits.
|
||
|
|
* 06-Aug-1990 davegi Added check for no arguments
|
||
|
|
* 03-Mar-1987 danl Update usage
|
||
|
|
* 17-Feb-1987 BW Move strExeType to TOOLS.LIB
|
||
|
|
* 18-Jul-1986 DL Add /t
|
||
|
|
* 18-Jun-1986 DL handle *. properly
|
||
|
|
* Search current directory if no env specified
|
||
|
|
* 17-Jun-1986 DL Do look4match on Recurse and wildcards
|
||
|
|
* 16-Jun-1986 DL Add wild cards to $FOO:BAR, added /q
|
||
|
|
* 1-Jun-1986 DL Add /r, fix Match to handle pat ending with '*'
|
||
|
|
* 27-May-1986 MZ Add *NIX searching.
