splitting strings


hi

this must be one of the easiest ones ever:
I have a string: "danyXmarryXbarry"

and I would like to split it into parts, "X" as the delimiter, so that I will have this:
$a[0]="dany"
$a[1]="marry"
$a[2]="barry"

isn't there something simply as the split function in Perl to do it? without getting onto complicated regex sed commands?

This should do it:-
Code:
str="danyXmarryXbarry"

a=($(echo $str | tr "X" " "))

thanks.
now just tell me, where was the last part, "barry", stored?
$a is now "dany"
there is no $a[2], $a{2}, or $a(2)....

To reference arrays in bash you have to use the format "${a[x]}"

So in this example we get:-
Code:
ahh@desktop ~ $ str=dannyXmarryXbarry;  a=($(echo $str | tr "X" " ")); echo ${a[0]}
danny
ahh@desktop ~ $ str=dannyXmarryXbarry;  a=($(echo $str | tr "X" " ")); echo ${a[1]}
marry
ahh@desktop ~ $ str=dannyXmarryXbarry;  a=($(echo $str | tr "X" " ")); echo ${a[2]}
barry
