I set my path environment variable in c shell, using the
syntax below
setenv PATH "${PATH}:/usr/local:/usr/local/bin"
and placed this in $HOME/.login
$HOME/.cshrc
and /etc/.login
/etc/.cshrc

Hi,
How does the PATH and MANPATH environment variable get set?
I want to add "/opt/SUNWspro/bin" to the search path for all the users. Where can I access this variable.

For some reason something has changing in my AIX environment where when I type:
ACLEDIT filename
...I get:

I know I need to reset the EDITOR variables path to /usr/bin/vi but I can't remember the syntax anyone? (2 Replies)
I've noted that in order to use commands like ifconfig, I have to prefix the commands with the directory.
/etc/profile shows that the paths should be part of the PATH environment variable; any idea where the bug is?

Hi,
I've read forums far and wide trying to learn how to append to my PATH in Solaris 9 and every time I think I am close I discover my system is not configured the same. Its so frustrating because this all stems from a new server I am trying to setup identical to the production machine. (Of... (5 Replies)
I am looking to parse a text file output and set variables based on what is cropped from the parsing.
Below is my script I am looking to add this feature too.

Hi Folks -
I was wondering if you could help convert batch code in Linux? For instance, I use the following piece of code in DOS to find a file/executable, and then the FULL path as a variable.
::-- If startMaxl.exe exists, set full path --::

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
