1.GNU Bash removes blank spaces and tabs

Hello,

With GNU bash, version 3.00.16(1)-release (i386-redhat-linux-gnu) :

# str="1<SP><SP>2<TAB>3"
# echo ${#str}
# 6

So far, so good. But :

# echo ${str}
# 1<SP>2<SP>3

Someone have an explanation ?

Thanks,

Christian

2.read command removes leading spaces - how to avoid?

How can I get each line of a file subsequently into a shell without 
loosing leading spaces?

Example: script.sh

#! /bin/bash
while read line
do
     echo "${line}"
done < $1


 > script.sh script.sh
outputs:

#! /bin/bash
while read line
do
echo "${line}"
done < $1

3.reading a file which is in user space from kernel space

HI,

Can we read a file which is in user space from kernel space.
Idea is : This file is a configuration file which contains info which
is needed by the file system. so while mounting i want to read this
file and keep it in memory.

4.Read chopping off space, and READ-ing binary data

Hi,
If I have a string " doggy" and I READ it into var, var ends up as
"doggy", with the leading spaces chopped off.
How do I stop this behaviour? (Is it the IFS environment variable?)

Also, does anything special have to be done to get READ to take in
Binary data, i.e. anything in the whole 0-255 ASCII range?



Thanks.

5.Read spaces with "read"

Hi,

Given the program below:



m3vmsa3.BIpex /tmp > cat kk.sh

cat foo|read
print ">>>${REPLY}<<<"


m3vmsa3.BIpex /tmp > cat foo

Thanks in advance,

6. Replace tab character with spaces

7. Replace N leading tabs with 2N spaces

8. TAB instead of 8 spaces??
