Hello, can someone please explain to me why this happens:
Code:
myserver#echo "$nothing"
myserver#if [ -z ${nothing} ]; then echo "nothing is a zero length string"; fi
nothing is a zero length string
myserver#if [ -n ${nothing} ]; then echo "nothing is also a non-zero length string, apparently"; fi
nothing is also a non-zero length string, apparently
Surely an undefined variable cannot be both zero-length and non-zero-length at the same time? I always have problems with the -n test flag - does it actually work?

Hi
lets say i have a variable
output="string"
how can you find the length of the string contained in this variable? i guess "wc" cannot be used. its only for files. (8 Replies)
I've never tested file length with shell before and I'm having problems. What I'm doing is testing $filename and $filename.bak to see if there is a difference. so I use 'diff' for that and send it to an output file 'dif.txt'. Now I wanna see if the length of 'dif.txt' is zero or not. that's where... (1 Reply)

Hello, Unix-Forums!
Is there a command that can check how long a user-entered string is?
Please don't give me a code, just the name of the command (playing around yourself is much more fun than just pasting code)
edit: I'm sorry, first hit of the forum search gave me the answer. (1 Reply)

SMBTORTURE(1) Test Suite SMBTORTURE(1)NAME
smbtorture - Run a series of tests against a SMB server
SYNOPSIS
smbtorture {//server/share} [-d debuglevel] [-U user%pass] [-k] [-N numprocs] [-n netbios_name] [-W workgroup] [-o num_operations]
[-e num files(entries)] [-O socket_options] [-m maximum_protocol] [-L] [-c CLIENT.TXT] [-t timelimit] [-C filename] [-A]
[-p port] [-s seed] [-f max_failures] [-X] {BINDING-STRING|UNC} {TEST1} [TEST2] [...]
DESCRIPTION
smbtorture is a testsuite that runs several tests against a SMB server. All tests are known to succeed against a Windows 2003 server (?).
Smbtorture's primary goal is finding differences in implementations of the SMB protocol and testing SMB servers.
Any number of tests can be specified on the command-line. If no tests are specified, all tests are run.
If no arguments are specified at all, all available options and tests are listed.
Binding string format
The binding string format is:
TRANSPORT:host[flags]
Where TRANSPORT is either ncacn_np for SMB, ncacn_ip_tcp for RPC/TCP or ncalrpc for local connections.
'host' is an IP or hostname or netbios name. If the binding string identifies the server side of an endpoint, 'host' may be an empty
string.
'flags' can include a SMB pipe name if using the ncacn_np transport or a TCP port number if using the ncacn_ip_tcp transport, otherwise
they will be auto-determined.
other recognised flags are:
sign
enable ntlmssp signing
seal
enable ntlmssp sealing
connect
enable rpc connect level auth (auth, but no sign or seal)
validate
enable the NDR validator
print
enable debugging of the packets
bigendian
use bigendian RPC
padcheck
check reply data for non-zero pad bytes
For example, these all connect to the samr pipe:
o ncacn_np:myserver
o ncacn_np:myserver[samr]
o ncacn_np:myserver[\pipe\samr]
o ncacn_np:myserver[/pipe/samr]
o ncacn_np:myserver[samr,sign,print]
o ncacn_np:myserver[\pipe\samr,sign,seal,bigendian]
o ncacn_np:myserver[/pipe/samr,seal,validate]
o ncacn_np:
o ncacn_np:[/pipe/samr]
o ncacn_ip_tcp:myserver
o ncacn_ip_tcp:myserver[1024]
o ncacn_ip_tcp:myserver[1024,sign,seal]
o ncalrpc:
UNC Format
The UNC format is:
//server/share
OPTIONS -d debuglevel
Use the specified Samba debug level. A higher debug level means more output.
-U user%pass
Use the specified username/password combination when logging in to a remote server.
-k
Use kerberos when authenticating.
-W workgroup
Use specified name as our workgroup name.
-n netbios_name
Use specified name as our NetBIOS name.
-O socket_options
Use specified socket options, equivalent of the smb.conf option "socket options". See the smb.conf(5) manpage for details.
-m max_protocol
Specify the maximum SMB dialect that should be used. Possible values are: CORE, COREPLUS, LANMAN1, LANMAN2, NT1
-s seed
Initialize the randomizer using seed as seed.
-L
Use oplocks.
-X
Enable dangerous tests. Use with care! This might crash your server...
-t timelimit
Specify the NBENCH time limit in seconds. Defaults to 600.
-p ports
Specify ports to connect to.
-c file
Read NBENCH commands from file instead of from CLIENT.TXT.
-A
Show not just OK or FAILED but more detailed output. Used only by DENY test at the moment.
-C filename
Load a list of UNC names from the specified filename. Smbtorture instances will connect to a random host from this list.
-N numprocs
Specify number of smbtorture processes to launch.
-o num_operations
Number of times some operations should be tried before assuming they're output is consistent (default:100).
-e num_files
Number of entries to use in certain tests (such as creating X files) (default: 1000).
-f max_failures
Number of failures before aborting a test (default: 1).
