Solaris limitations

Hi, I recently started working with Solaris, and what I noticed is that a lot of commands I used to regularly use don't work, like sed -i and grep -r. I have found work arounds for these problems though but it's a pain in the ass. I'm just wondering why they decided not to include these handy...

slabtop

SLABTOP(1)							   User Commands							SLABTOP(1)

NAME

       slabtop - display kernel slab cache information in real time

SYNOPSIS

       slabtop [options]

DESCRIPTION

       slabtop	displays detailed kernel slab cache information in real time.  It displays a listing of the top caches sorted by one of the listed
       sort criteria.  It also displays a statistics header filled with slab layer information.

OPTIONS

       Normal invocation of slabtop does not require any options.  The behavior, however, can be fine-tuned by specifying one or more of the  fol-
       lowing flags:

       -d, --delay=N
	      Refresh the display every n in seconds.  By default, slabtop refreshes the display every three seconds.  To exit the program, hit q.

       -s, --sort=S
	      Sort by S, where S is one of the sort criteria.

       -o, --once
	      Display the output once and then exit.

       -V, --version
	      Display version information and exit.

       -h, --help
	      Display usage information and exit.

SORT CRITERIA

       The  following are valid sort criteria used to sort the individual slab caches and thereby determine what are the "top" slab caches to dis-
       play.  The default sort criteria is to sort by the number of objects ("o").

       The sort criteria can also be changed while slabtop is running by pressing the associated character.

       character   description		      header
       a	   number of active objects   ACTIVE
       b	   objects per slab	      OBJ/SLAB
       c	   cache size		      CACHE SIZE
       l	   number of slabs	      SLABS
       v	   number of active slabs     N/A
       n	   name 		      NAME
       o	   number of objects	      OBJS
       p	   pages per slab	      N/A
       s	   object size		      OBJ SIZE
       u	   cache utilization	      USE

COMMANDS

       slabtop accepts keyboard commands from the user during use.  The following are supported.  In the case of letters, both cases are accepted.

       Each of the valid sort characters are also accepted, to change the sort routine. See the section SORT CRITERIA.

       <SPACEBAR>
	      Refresh the screen.

       Q      Quit the program.

FILES

       /proc/slabinfo
	      slab information

SEE ALSO

       free(1), ps(1), top(1), vmstat(8)

NOTES

       Currently, slabtop requires a 2.4 or later kernel (specifically, a version 1.1 or later /proc/slabinfo).  Kernel 2.2 should be supported in
       the future.

       The  slabtop statistic header is tracking how many bytes of slabs are being used and it not a measure of physical memory.  The 'Slab' field
       in the /proc/meminfo file is tracking information about used slab physical memory.

AUTHORS

       slabtop was inspired by Martin Bligh's perl script, vmtop.
