#Sorry that was me getting carried away and cut and pasting the wrong thing

#The real problem seems to be that :
|
||
|
|
#BEGIN {
|
||
|
|
#for (i=1;i<10;i++){
|
||
|
|
# while((getline < "hello.txt")>0){
|
||
|
|
# print $0
|
||
|
|
# }
|
||
|
|
# close("hello.txt")
|
||
|
|
# }
|
||
|
|
#}
|
||
|
|
#works (printing the contents of hello.txt 9 times), where as:-
|
||
|
|
#
|
||
|
|
#END{
|
||
|
|
#for (i=1;i<10;i++){
|
||
|
|
# while((getline < "hello.txt")>0){
|
||
|
|
# print $0
|
||
|
|
# }
|
||
|
|
# close("hello.txt")
|
||
|
|
# }
|
||
|
|
#}
|
||
|
|
#
|
||
|
|
#doesn't, (it prints out hello.txt once followed by the iteration numbers
|
||
|
|
#from 1 to 9).
|
||
|
|
#The only difference is that one is in the BEGIN block and one in the END
|
||
|
|
#block.

#Sorry about the first post, I'm not a bad awk programmer, just a tired one
