Reading files in script from another directory
Hi

I'm trying to call my files from different directories in my script.

Can you please help me.

Here is my script:

Code:
 
#!/bin/bash
#---------------------------------------------------------------------------------------------------------------------- 
#This script allows the user to input the cellid and new parameter value, the old csv file and what the user 
#would like to name the new csv file. The changed data is then piped to the new file and ready for the import process
#
#./csv_file_change.sh -i -p -o -n
#
#-----------------------------------------------------------------------------------------------------------------------
id="$id"
paramval="$paramval"
oldfile="$oldfile"
newfile="$newfile"
function displayHelp()
{
echo ""
echo " Usage: csv_file_change [ -i -p -o -n ]"
echo ""
echo " -i, --id identified by the cellid "
echo " -p, --paramval identified by the new parameter value "
echo " -o, --oldfile identified by the name of the original file "
echo " -n, --newfile identified by the name of the new altered file "
echo " -h, --help identified by the help menu "
echo ""

}
while getopts " i: p: o: n: h " option
do
case $option in
i ) id="$OPTARG";;
p ) paramval="$OPTARG";;
o ) oldfile="$OPTARG";;
n ) newfile="$OPTARG";;
h ) displayHelp;exit;;
? ) displayHelp;exit;;



esac;
done
 
awk -F, -v id=$id -v paramval=$paramval -v oldfile=$oldfile -v newfile=$newfile '$2==id{$3=paramval}1' OFS="," $oldfile > $newfile

My directory that the file is in is called:

Code:
/C:\cygwin\var\local\dsx\csv

I want to write my resulting files to this directory

Code:
/C:\cygwin\var\local\dsx\output

Can you help me please help me

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.
	      915 of 1612581 (0.057%)
