how to read double consecutive space in filename for bash shell
Hello,
Im using cygwin app which we use the bash shell for scripting.
Im trying to read a filename with consecutive spaces on the filename
ex: filename<space><space>1.txt
ls -lrt filename<space><space>1.txt is working but when I pull that from a file and place it into variable. it reads only as single space: filename<space>1.txt
ex:
cat samp.txt
output:
1:filename<space><space>2.txt
2:filename<space><space>1.txt
3:filename<space><space>3.txt
var1=`cat samp.txt |sed -n -2p |awk '{print $NF}'`
echo $var1
output:
filename<space>1.txt
Please advice how to read double consecutive spaces. Is there any escape characters?

bdiff
bdiff(1) User Commands bdiff(1)
NAME
bdiff - big diff
SYNOPSIS
bdiff filename1 filename2 [n] [-s]
DESCRIPTION
bdiff is used in a manner analogous to diff to find which lines in filename1 and filename2 must be changed to bring the files into agree-
ment. Its purpose is to allow processing of files too large for diff. If filename1 (filename2) is -, the standard input is read.
bdiff ignores lines common to the beginning of both files, splits the remainder of each file into n-line segments, and invokes diff on cor-
responding segments. If both optional arguments are specified, they must appear in the order indicated above.
The output of bdiff is exactly that of diff, with line numbers adjusted to account for the segmenting of the files (that is, to make it
look as if the files had been processed whole). Note: Because of the segmenting of the files, bdiff does not necessarily find a smallest
sufficient set of file differences.
OPTIONS
n The number of line segments. The value of n is 3500 by default. If the optional third argument is given and it is numeric, it is
used as the value for n. This is useful in those cases in which 3500-line segments are too large for diff, causing it to fail.
-s Specifies that no diagnostics are to be printed by bdiff (silent option). Note: However, this does not suppress possible diagnostic
messages from diff, which bdiff calls.
USAGE
See largefile(5) for the description of the behavior of bdiff when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
