Question

I have

char *path;

and I store the string “/home/juggler/file1.txt” in path. How do I truncate path so that I just have the parent of the last file/directory? In the example I would like to truncate path to “/home/juggler”

I was thinking of counting the number of characters(count) from the end to the last “/” and the copy the (length of path)-(count) to another string.

Thanks

Try dirname(3) since you are on Linux. Being specified by SUSv3, it’s quite portable.

char *dirname(char *path);

In the usual case, dirname() returns the string up to, but not
including, the final ‘/’.
