wingrass: please add tac and seq to extrabin

[hamish]

Hi,

tac.exe and seq.exe are no longer shipped with wingrass. (I'm not sure if tac ever was)

I'm pretty sure seq used to be there (in msys/bin/?) but it seems to have gone away.

if it's an easy thing to do, could we install these unix powertools to msys/bin/ or extrabin/?

thanks, Hamish

more.exe is missing from the wingrass bash prompt too.

thanks

Can a winGRASS user please check if these commands are now in the installer?

• bc
• more
• seq
• tac
• xml2

? Thanks.

tac and seq aren't specified by POSIX. Any scripts which use them should be modified to work without them.

Not only is seq trivial to implement as a shell function, I can't find anything which actually uses it.

The only user of tac appears to be v.in.mapgen, which provides its own implementation (using awk) as a fallback.

I would expect that users wants to use them in their own scripts, or their might be used in addons. The fact is that their are used in manual, however each just once/twice:

dist.../docs/html $ egrep -Irn "tac " .
./m.cogo.html:169:    m.cogo -l in=cogo.dat | tac | awk '
./m.cogo.html:172:       END { printf("L %d\n", R) }' | tac | \

dist.../docs/html $ egrep -Irn "seq " .
./d.out.gpsdrive.html:139:for i in `seq 1 $panels_ew`;
./d.out.gpsdrive.html:142:  for j in `seq 1 $iter`;

I would just ignore these two.
