gene@coyote:~/src/build$ type wget
wget is hashed (/usr/bin/wget)

What the heck does that mean?
no extra charge:

file /usr/bin/wget
/usr/bin/wget: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), 
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for 
GNU/Linux 2.6.32,

gene@coyote:~/src/build$ id

gene@coyote:~/src/build$ ls -ld

How would that be diagnosed?

1T drive, not likely.

df -h grep sda
/dev/sda5       1.8T  291G  1.4T  18% /
/dev/sda1       922M  183M  677M  22% /boot
/dev/sda3        46G  4.7G   39G  11% /var

Diagnostic for that?
