While playing around with getting host entries to work with ldap, I found that my previous code for using gethostbyname was not running clean on puias6. Here is an updated version
#include
#include
#include
#include
#include
#includeint main(int argc, char **argv) {
int i;
struct hostent *hp;
struct in_addr **addr_list;if (argc < 2) {
printf("Usage: %s hostname\n", argv[0]);
exit(1);
}
We store our host information in ldap. Previously using ldap for host lookups was done by adding the appropriate entries to /etc/ldap.conf and changing nsswitch.conf.
With 6, nss_ldap has been replaced by nslcd, so I needed to change our setup a little.
I put the following into nslcd.conf
A friend of mine was talking about his design for a shell that would allow you to programatically reuse arguments. I started looking and found that bash can do this but not programatically (at least as far as I know). The syntax was slighty confusing but here is the summary, it blew my mind when I started using it (but I'll probably forget it again soon enough, like all the awesome things you can do in vi if you can remember...)
Here goes, lets copy a file from a deeply nested path to our location by first tab-completing the filename with ls
alias fl='(for file in `find .??* * -maxdepth 0 -type d`; do du -hs $file 2>/dev/null; done) |sort -h -k 1'
