Like most every system administrator, I have a collection of little scripts. This is an index to the ones I've actually written something about, mostly pointing to discussions in my techblog.
| addr | Turn full hostnames into IP addresses (via DNS lookups). |
| countup | Feed field's output to howmany. |
| expsyslog.pl | Expand 'last message repeated N times' syslog messages. |
| field | Extract the given field(s) from stdin. |
| howmany | Sum up how many times lines occur on stdin. |
| nsaddrs | Report the IP addresses of the nameservers for a particular zone. |
| nsdig | Run dig against the nameservers for a particular zone. |
| sdig | dig with short output. |
| wcat | Dump a URL to standard out. |
People on GPU can usually find these in /u/cks/bin or /u/cks/adm
(depending). (/u/cks/bin has a hysterically out of date README for
other things.)
