I provided --mode a-w to remove "w" bit from "all". But it only removed for others and not for the "user". I was hoping to see 555 and instead I see 755.
Why? My umask, BTW, is set to 022.

Reason: Please use code tags
cat .servers | while read LINE; do
ssh jason@$LINE $1
done
exit 1
./command.ksh "ls -l ~jason"
Why does this ONLY iterate on the first server in the list? It's not doing the command on all the servers in the list, what am I missing?
Thanks!

Howdie everyone...
I have a shell script RemoveFiles.sh
Inside this file, it only has two commands as below:

I have a folder that I need to search for new files and copy on the latest. I've been using "-mtime -1" in my command line but it doesn't seem to work.
I've been meaning to fine a different script because files are dropped into the folder all day long and because of the -mtime, I've only be... (19 Replies)
Hi!
I have a somehow big file (almost 3000 lines long and thirteen columns). Some lines have no value at all or, at least, are incomplete. The columns' values that have no data are marked with a "-" and the corresponding line (the line that owns that value) should be discarded and not used.

Hi,
I am using korn shell.

To the above script, I passed 2 parameters and the program control doesn't enter inside "until" loop. If I change it to until ] then it does work.

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.
915 of 1612581 (0.057%)
