InsTar

Mon, 15 May 2006 10:21:00 GMT

InsTar was written to simplify the process of installing a package from a source tarball. To install from a tarball is normally a five step process:$ tar -xzvf foobar.tar.gz$ cd foobar$ ./configure$ ./make$ ./make installInsTar reduces this to one step:$ instar foobarThe usual way to run InsTar is to run it with one parameter - the name of the file to install. Note that the extension (.tar.gz, .tar.bz2, etc) should not be included. If there is an error, InsTar will exit with a short explanation of the problem. InsTar should be run as root, otherwise it will fail when it gets to the make install step.Other parameters are:$ instar --helpor$ instar -hwill display a short help$ instar --installwill copy instar to /bin/instar and make it executable by everyone.$ instar --removewill delete the file /bin/instar$ instar --versionwill display some version information and exit.

hup_inetd

Mon, 15 May 2006 10:21:00 GMT

A simple one-liner I came up with for sending the 'kill-HUP' signal to inetd after making changes. No need to look up the PID for inetd, this does it for you, and let's you know when it's done. Tested under GNU/Linux using the bash shell.Use it as a function for your profile or bashrc script for handy reference. Must have root privelege for it to work.

passgen

Mon, 15 May 2006 10:21:00 GMT

passgen is a utility for generating a list of 15 random passwords. The defaultpasswords generated are 8 characters in length, using normal alphanumericcharacters. However, the length and the strength of the passwords can bemodified with command line options. Read the 'print_help()' function for moredetails.The code for this version was greatly optimized for parsing the command lineoptions, reducing the size by more than one-third, and the 'print_help()'function was also enhanced.This script also tests for the presence of /dev/urandon. If found, it willuse that device for creating the passwords. Otherwise it will use /dev/random.Loosely based on the ptool script found at SourceForge.net by Anthony Briggs.

cpdate

Mon, 15 May 2006 10:21:00 GMT

A slightly different and independently created cpdate the one that exists here already. My version does not fo the subdir stuff, but checks if the file exists to avoid overwriting it, and automatically goes to the "dateTtime" version in that case.The "note" case will also add a date suffix in the same manner.

IDH - Interactive Directory History for Bash >=2.04

Mon, 15 May 2006 10:21:00 GMT

This is a collection of Bash functions and environment variables which implement a simple way of interacting with Bash's directory history.Here's a screenshot of my prompt (used below to illustrate features): <6> ~ <5> ~/tt.sandbox/tt <4> ~/newMM <3> /cvsroot/CVSROOT <2> ~/tt.sandbox/CVSROOT <1> ~/tt.sandbox ~/newMM/cnlp/ sarowe@katzer[1049]$ The above is nothing special, of course: it's just a reverse listing of the DIRSTACK[] array; the PROMPT_COMMAND env. var. is set to 'rds', which is the name of the function which prints this. The user can toggle this display by invoking the 'tddh' (Toggle DISPLAY_DIR_HISTORY) function.The actual features are (examples refer to the above screenshot): - Quick return to an entry in the history with new 'back' command ('back 3' will change the current directory from '~/newMM/cnlp' to '/cvsroot/CVSROOT'). - Unique history maintenance, including tilda-expansion. - Removal of unwanted entries in the history with new 'drop' command ('drop 1-4 6' will leave only '~/tt.sandbox/tt' in the history). - Automatic removal of non-existent directories from history (after directory deletion, etc.).Assumptions: - You'll visit less than 100 directories in a given session.This stuff was inspired by the directory history popup windows available under the 4DOS shell.I enable all this by sticking these functions and env. var. settings in my .bashrc.Enjoy,Steve Rowe
