Question assign value to variable is not working
Hi Smilie

The next script campares two files File1-Line1 vs File2-Line1, File1-Line1 vs File2-Line2... only if line contains "AS-", if LineX is not in File2 writes in aux, but "valor" is allways=1 never changes! Smilie What is wrong?
valor changes to 0 before break, after brake is again 1

#!/bin/ksh

echo > aux

while read label
do
valor=1
echo $label | grep "AS-"
if [ $? -eq 0 ]
then
while read labelold
do
if [ "${label}" = "${labelold}" ]
then
#echo "encon" >aux2
valor=0
echo $valor
break
fi
echo $valor #<--- Allways is 1 Smilie
done < hosts.old
if [$valor -eq 1]
then
echo "$label" >> aux
fi
fi
done < hosts

gfs2_tool

gfs2_tool(8)						      System Manager's Manual						      gfs2_tool(8)

NAME

       gfs2_tool - interface to gfs2 ioctl/sysfs calls

SYNOPSIS

       gfs2_tool COMMAND [OPTION]...

DESCRIPTION

       gfs2_tool is an interface to a variety of the GFS2 ioctl/sysfs calls. Some of the functions of gfs_tool have been replaced by standard sys-
       tem tools such as mount and chattr, so gfs2_tool doesn't have as many options as gfs_tool used to.

COMMANDS

       clearflag Flag File1 File2 ...
	      Clear an attribute flag on a file. This is now obsolete and kept only for backward compatibility, chattr is  the	preferred  way	to
	      clear attribute flags. See setflag for available flags. This option will probably be removed at a future date.

       freeze MountPoint
	      Freeze (quiesce) a GFS2 cluster.

       gettune MountPoint
	      Print  out  the  current	values	of  the tuning parameters in a running filesystem. A better source of similar (more comprehensive)
	      information is that in the /proc/mounts file. Running the mount command with no arguments will also provide  the	same  information.
	      This option is considered obsolete and will probably be removed at some future date.

       journals MountPoint
	      Print out information about the journals in a mounted filesystem.

       lockdump MountPoint
	      Print  out information about the locks this machine holds for a given filesystem. This information is also available via the debugfs
	      glock dump file, and accessing that file is the preferred method of obtaining a dump of the glock state.

       sb device proto [newvalue]
	      View (and possibly replace) the name of the locking protocol in the file system superblock.  The file system shouldn't be mounted by
	      any client when you do this.

       sb device table [newvalue]
	      View  (and  possibly  replace) the name of the locking table in the file system superblock.  The file system shouldn't be mounted by
	      any client when you do this.

       sb device ondisk [newvalue]
	      View (and possibly replace) the ondisk format number in the file system superblock.  The file system shouldn't  be  mounted  by  any
	      client when you do this.	No one should have to use this.

       sb device multihost [newvalue]
	      View  (and possibly replace) the multihost format number in the file system superblock.  The file system shouldn't be mounted by any
	      client when you do this.	No one should have to use this.

       sb device uuid [newvalue]
	      View (and possibly replace) the uuid in the file system superblock.  The file system shouldn't be mounted by any client when you	do
	      this.  The new uuid value should be in the standard uuid format.	For example: 1AEA8269-15C5-72BD-6D83-8720B17AA4EE

       sb device all
	      Print out the superblock.

       setflag Flag File1 File2 ...
	      Set  an  attribute  flag	on a file.  The currently supported flags are jdata, immutable, appendonly, noatime, and sync.	The chattr
	      command is the preferred way to set attributes on files. This option will probably be removed at a future date.

	      The jdata flag causes all the data written to a file to be journaled.  If the jdata flag is set  for  a  directory,  all	files  and
	      directories  subsequently  created within that directory are also journaled.  This behavior replaces the old inherit_jdata flag from
	      gfs.  Same as chattr +j.

	      The immutable flag marks the file immutable. The behavior is similar to the immutable flag in the  ext2/3  filesystems.	All  write
	      access is denied.  Same as chattr +i.

	      The appendonly flag causes all data to be written at the end of the file.  Same as chattr +a.

	      The noatime flag disables updates to the file's access time.  Same as chattr +A.

	      The sync flag causes data written to the file to be sync'ed to stable storage immediately.  Same as chattr +S.

       settune MountPoint parameter newvalue
	      Set  the	value  of tuning parameter.  Use gettune for a listing of tunable parameters. The mount -oremount command is the preferred
	      way to set the values of tunable parameters. At some future stage, when all parameters can be set via mount,  this  option  will	be
	      removed.

       unfreeze MountPoint
	      Unfreeze a GFS2 cluster.

       version
	      Print out the version of GFS2 that this program goes with.

       withdraw MountPoint
	      Cause  GFS2  to abnormally shutdown a given filesystem on this node.  This feature is only useful for testing and should not be used
	      during normal filesystem operation.
