Also if anyone could correct my bash method I wuoldnt mind knowing how to do it in that too please. I tried while, repeat, etc and couldnt seem to get it.

from man seq:
-w, --equal-width
equalize width by padding with leading zeroes

not sure why it crashes, perhaps seq can't deal with so many numbers?

Equal width wouldn't affect it. (I think anyway)

THat's for use with different sizes,

e.g. 1 and 100 because 001 100

As the numbers he has are same size it wouldn't change them :(

I just did:
seq -w 0400 0499
and it seemed ok

you could also do:

Code:

---

!#/usr/bin/python
count = 400000000
while count <= 499999999:
      count = count + 1
      print '0%s' % (count)

Ah fair enough, maybe it does it different as you already used the following 0s :( Didn't like it for me!

that took about 3min to run on Intel(R) Core(TM)2 Duo CPU T5870 @ 2.00GHz


tail file2
0499999991
0499999992
0499999993
0499999994
0499999995
0499999996
0499999997
0499999998
0499999999
0500000000


ls -lh file2
-rw-rw-r--. 1 cybernerd cybernerd 1.1G Jun 30 17:06 file2

this is either a quad core or its dualcore with hyperthreading but it seems i have 4 cpus

task manager shows cmd.exe isnt using more than 12%

Ill try it in python later see if it will run faster but im guessing its nearly done. It wont open in np++ any more

Notepad++ won't be able to handle a file that large.

time python ./file > file2

real 2m17.287s
user 2m10.026s
sys 0m4.393s

I cant get the python one to work, it just displays 50000000 for me..

root@ubuntu:~# ./test.py
0500000000
root@ubuntu:~# cat test.py
#!/usr/bin/python
count = 400000000
while count <= 499999999:
count = count + 1
print '0%s' % (count)
root@ubuntu:~#

You're running it directly, not outputting it? Will only show end result I'd assume?

Steve

but it takes <20 sec to display the 50000000 it cant possibly iterate them all in that time

root@ubuntu:~# time ./test.py
0500000000

real 0m13.115s
user 0m12.870s
sys 0m0.020s

also >> to a file oinly shows the 1 line

thats the dos batch file just finished :P

On this occasion it looks like it's the opposite result. ;)

1.2GB text file compresses into a 13MB rar file.. wow.
