comparing scalars contaning "DOUBLE QUOTES" as data

Hello to all,

Does anyone know the solution ?

Two strings A and B are present. I want to check whether B is a Substring of A.

1. The value of A is - 29 * * * /bin/ls "test" "tmp*" "log*"
(Note: Pl note that A contains DOUBLEQUOTES, ASTERISK & FRONTSLASH)

2. The value of B is - /ls "test" "tmp*" "log*"
(Note: again B contains DOUBLEQUOTES, ASTERISK & FRONTSLASH)

Since the variable scalars A and B have DOUBLEQUOTES as a part of the data stored "=~" operator is not working.

[ $A =~ $B ] - results in error..

Is there any other way (any sed/awk/perl one liners). Requesting help to solve this.

Thanks
rssrik

xfs_estimate(8) 					      System Manager's Manual						   xfs_estimate(8)

NAME
xfs_estimate - estimate the space that an XFS filesystem will take SYNOPSIS
xfs_estimate [ -h ] [ -b blocksize ] [ -i logsize ] [ -e logsize ] [ -v ] directory ... xfs_estimate -V DESCRIPTION
For each directory argument, xfs_estimate estimates the space that directory would take if it were copied to an XFS filesystem. xfs_esti- mate does not cross mount points. The following definitions are used: KB = *1024 MB = *1024*1024 GB = *1024*1024*1024 The xfs_estimate options are: -b blocksize Use blocksize instead of the default blocksize of 4096 bytes. The modifier k can be used after the number to indicate multiplica- tion by 1024. For example, xfs_estimate -b 64k / requests an estimate of the space required by the directory / on an XFS filesystem using a blocksize of 64K (65536) bytes. -v Display more information, formatted. -h Display usage message. -i, -e logsize Use logsize instead of the default log size of 1000 blocks. -i refers to an internal log, while -e refers to an external log. The modifiers k or m can be used after the number to indicate multiplication by 1024 or 1048576, respectively. For example, xfs_estimate -i 1m / requests an estimate of the space required by the directory / on an XFS filesystem using an internal log of 1 megabyte. -V Print the version number and exits. EXAMPLES
% xfs_estimate -e 10m /var/tmp /var/tmp will take about 4.2 megabytes with the external log using 2560 blocks or about 10.0 megabytes % xfs_estimate -v -e 10m /var/tmp directory bsize blocks megabytes logsize /var/tmp 4096 792 4.0MB 10485760 % xfs_estimate -v /var/tmp directory bsize blocks megabytes logsize /var/tmp 4096 3352 14.0MB 10485760 % xfs_estimate /var/tmp /var/tmp will take about 14.0 megabytes xfs_estimate(8)
