Display a list of RPMs installed on a particular date

Find out which RPMs were installed on a particular date.

These would (naturally) include update RPMs.

This example shows searching for "Thu 05 Mar" (with grep).

Alternatively, pipe it to less so you can search inside less (with less's neat text highlighting of the search term):

rpm -qa --queryformat '%{installtime} \"%{vendor}\" %{name}-%{version}-%{release} %{installtime:date}\n' | less # (this example) search term: Thu 05 Mar

Use lynx to run repeating website actions

This command will tell lynx to read keystrokes from the specified file - which can be used in a cronjob to auto-login on websites that give you points for logging in once a day *cough cough* (which is why I used -accept_all_cookies).

For creating your keystroke file, use:

lynx -cmd_log yourfile

#

Using the "#" in shell is surprisingly useful.

Some of the uses I found:

a) As a visible copy buffer in shell history (caveat: do not use for passwords :-)

b) To build complex commands until ready then hit the HOME, DEL, ENTER keys to run it

c) Placing reference data into shell history (search for tags with CTRL-R TAGNAME)

d) Putting aside a "work in progress" command to focus on another task (HOME # ENTER)

Copy all files. All normal files, all hidden files and all files starting with - (minus).

./* is for copying files starting with -

.[!.]* is for copying hidden files and avoiding copying files from the parent directory.

..?* is for copying files starting with .. (avoids the directory ..)

/path/to/dir the path to the directory where the files should be copied

Can also be used as a script. Input argument is /path/to/dir

in tcsh, replace .[!.]* with .[^.]*

iso-8859-1 to utf-8 safe recursive rename

This command is a powerful "detoxifier" that eliminates special chars, spaces and all those little chars we don't like. It support several "sequences" so be sure to check your /usr/local/etc/detoxrc while at it... and maybe define your own

There is no need to 'zcat textfile.gz | less' with newer distros. This is useful for reading archived log files without having to extract, read, and zip when done.

Quickly add user accounts to the system and force a password change on first login

This command is a bit Linux specific, as --stdin doesn't exist for passwd on many Unix machines. Further, useradd is high level in most distributions and Unix derivatives except for the Debian family of distros, where adduser would be more appropriate. The last bit, with chage, will force the user to change their password on new login.
