/* ls - fancy schmancy dir list program
|
||
|
|
*
|
||
|
|
* HISTORY:
|
||
|
|
* 17-Mar-87 danl Added q switch
|
||
|
|
* 4/15/86 daniel lipkie Allow /s as well as /1 (one) to do single col
|
||
|
|
* 4/23/86 daniel lipkie Add /v switch
|
||
|
|
* 5/02/86 daniel lipkie savepath, do strlen(pat), not strlen(*pat)
|
||
|
|
* 5/05/86 daniel lipkie Allow - as well as / as switch char
|
||
|
|
*
|
||
|
|
* 31-Jul-1986 mz Add in net aware-ness. ls \\mach\path works now.
|
||
|
|
* Discard bogus C stat() function and do times correctly.
|
||
|
|
* 01-Aug-1986 dl If invokes as l, then do ls /l
|
||
|
|
* 23-Jan-1987 bw Add 286DOS support
|
||
|
|
* 30-Oct-1987 bw Changed 'DOS5' to 'OS2'
|
||
|
|
* 08-Dec-1988 mz Chance to use OS2.H
|
||
|
|
*
|
||
|
|
* 03-Aug-1990 davegi Removed 'F' from [s]printf format
|
||
|
|
* descriptors (OS/2 2.0)
|
||
|
|
* Changed Move to memmove
|
||
|
|
* Removed redundant check for '-' switch character
|
||
|
|
* 18-Oct-1990 w-barry Removed 'dead' code.
