Find Man pages for everything in your $PATH

If I type 'man something', I want it to find the manpage in the same order as my PATH.

You can add something like this to your .bashrc

#

# Add my MacPorts, my personal utilities and my company utilities to my PATH.

export PATH=$PATH:/opt/local/bin:$HOME/bin:/our_company_utils/bin/

# Now set the manpath based on the PATH, after man(1) parses man.conf

# - No need to modify man.conf or manually modify MANPATH_MAP

# - Works on Linux, FreeBSD & Darwin, unlike /etc/manpaths.d/

# Must unset MANPATH first. MANPATH is set on some systems automatically (Mac),

# which causes manpath to ignore the values of PATH like /opt/local/bin (MacPorts).

# Also MANPATH may be deprecated. See "SEARCH PATH FOR MANUAL PAGES" in man(1)

unset MANPATH

# manpath acts differently on Solaris, FreeBSD, MacOSX & GNU. This works everywhere.

manpath >/dev/null

#

Note that MacOSX, FreeBSD & Linux have fancier ways to do some of this. (e.g. 'man --path' or 'man -q'), but this command is more universal and should work everywhere.

Don't spam root. Log your cronjob output to syslog

This command will log the output of your simple cronjobs to syslog, and syslog will take it from there. Works great for monitoring scripts which only produce simple output.

Advantages:

* This can be used by regular users, without modifying system files like /etc/syslog.conf

* Reduce cron spam to root@localhost (Please stop spaming the sysadmins)

* Uses common tools like syslog (and logrotate) so that you don't need to maintain yet another krufty logfile.

* Still ensures that the output is logged somewhere, for posterity. Perhaps it's stored the secure, central syslog server, for example.

* Seems to work fine on Ubuntu, CentOS, FreeBSD & MacOSX

Delete the previous entry in your history

I rarely need this, but I have a hard time remembering the command when I need it.

Admit it. This has happened to you. Yes this is bad, and you better clean up now.

Read info(1) pages using 'less' instead of GNU Texinfo

I like man pages, and I like using `less(1)` as my pager. However, most GNU software keeps the manual in the 'GNU Texinfo' format, and I'm not a fan of the info(1) interface. Just give me less.

This command will print out the info(1) pages, using the familiar interface of less!
