Is there a way to shorten these commands? because this script asks for a password 3 times
scp -p /usr/local/bin/${script_name} ${servername$iy]}://usr/local/bin/
ssh ${servernames} /usr/local/bin/${script_name}
ssh ${servernames} rm -f /usr/local/bin/${script_name}

Are there any documents available for checking the execution time taken by ksh commands?
My requirement is to fine tune a set of shell scripts having lot of "echos" and "date"s.
Is there a better replacement for the below code?.

Hi,
I am trying to execute a bunch of piped command which are stored in a variable, but only one command executed at a time, and rest of the pipes, commands and their arguments are considered as argument to the very first command.
Can you please help me in this?

I am trying to to this

I am using SED to edit a file (called file)
the file contains the word "ERROR"
and I want to use SED to:
1. Search for text "ERROR"
If found,
2. Append new line with text "hoi"
I tried:
sed 's/ERROR/ a\hoi' file

I get all the time the error

I need to run few commands in a ksh script sequentially.
Some of the commands are jobs submitted to the server and the consecutive commands are dependent on the completion of the jobs submitted to the server.
It works if i separate the commands into different files like this

I create commands within a pipe and finally want them to be executed instead of being displayed on the screen. What is the last stage in this pipe? I found by guessing that "ksh" is working, but is this the best to use here?
It boils down to this:
echo "print Hello World!"| kshWhat is the... (15 Replies)

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.
