i have a problem in finding block of identical strings...i solved the problem in finding consecutive identical words and now i want to expand the code in order to find and remove consecutive identical block of strings...
for example the awk code removing consecutive identical word is:
Code:
#!/usr/bin/awk -f
BEGIN{
RS="[[:space:]]+";
ORS=""
}
match($0,/^([[:punct:]]*)([^[:punct:]]+)([[:punct:]]*)$/,f){
if(x != f[2])
{
print y$0;z = FNR
}
x = f[2];
y = RT
}
END{
if(z != FNR)
print f[3]"\n"
}
input:
"ana are mere mere
mere si portocale
ion are prune prune."
output:
"ana are mere si portocale
ion are prune."
and now i want to expand the code to do the following:
input:
"ana are ana are mere
ion are prune ion are prune"
output:
"ana are mere
ion are prune"
thanks
