Hello all,
This beats me. I have a script that executes some commands and redirects their output to some text files that I will parse. The commands are along the lines of:
dsmadmc -id=admin -pa=admin -outfile=/home/tools/qlog.txt q log f=d
If I just run the script it works. If I execute... (2 Replies)

Hi all,
In bash scripting, I use to read files:
cat $file | while read line; do

doneHowever, it's a very slow way to read file line by line.
E.g. In a file that has 3 columns, and less than 400 rows, like this:
I run next script:

access.conf
ACCESS.CONF(5) Linux-PAM Manual ACCESS.CONF(5)NAME
access.conf - the login access control table file
DESCRIPTION
The /etc/security/access.conf file specifies (user/group, host), (user/group, network/netmask) or (user/group, tty) combinations for which
a login will be either accepted or refused.
When someone logs in, the file access.conf is scanned for the first entry that matches the (user/group, host) or (user/group,
network/netmask) combination, or, in case of non-networked logins, the first entry that matches the (user/group, tty) combination. The
permissions field of that table entry determines whether the login will be accepted or refused.
Each line of the login access control table has three fields separated by a ":" character (colon):
permission:users/groups:origins
The first field, the permission field, can be either a "+" character (plus) for access granted or a "-" character (minus) for access
denied.
The second field, the users/group field, should be a list of one or more login names, group names, or ALL (which always matches). To
differentiate user entries from group entries, group entries should be written with brackets, e.g. (group).
The third field, the origins field, should be a list of one or more tty names (for non-networked logins), host names, domain names (begin
with "."), host addresses, internet network numbers (end with "."), internet network addresses with network mask (where network mask can be
a decimal number or an internet address also), ALL (which always matches) or LOCAL. LOCAL keyword matches if and only if the PAM_RHOST is
not set and <origin> field is thus set from PAM_TTY or PAM_SERVICE". If supported by the system you can use @netgroupname in host or user
patterns. The @@netgroupname syntax is supported in the user pattern only and it makes the local system hostname to be passed to the
netgroup match call in addition to the user name. This might not work correctly on some libc implementations causing the match to always
fail.
The EXCEPT operator makes it possible to write very compact rules.
If the nodefgroup is not set, the group file is searched when a name does not match that of the logged-in user. Only groups are matched in
which users are explicitly listed. However the PAM module does not look at the primary group id of a user.
The "#" character at start of line (no space at front) can be used to mark this line as a comment line.
EXAMPLES
These are some example lines which might be specified in /etc/security/access.conf.
User root should be allowed to get access via cron, X11 terminal :0, tty1, ..., tty5, tty6.
+ : root : crond :0 tty1 tty2 tty3 tty4 tty5 tty6
User root should be allowed to get access from hosts which own the IPv4 addresses. This does not mean that the connection have to be a IPv4
one, a IPv6 connection from a host with one of this IPv4 addresses does work, too.
+ : root : 192.168.200.1 192.168.200.4 192.168.200.9
+ : root : 127.0.0.1
User root should get access from network 192.168.201. where the term will be evaluated by string matching. But it might be better to use
network/netmask instead. The same meaning of 192.168.201. is 192.168.201.0/24 or 192.168.201.0/255.255.255.0.
+ : root : 192.168.201.
User root should be able to have access from hosts foo1.bar.org and foo2.bar.org (uses string matching also).
+ : root : foo1.bar.org foo2.bar.org
User root should be able to have access from domain foo.bar.org (uses string matching also).
+ : root : .foo.bar.org
User root should be denied to get access from all other sources.
- : root : ALL
User foo and members of netgroup admins should be allowed to get access from all sources. This will only work if netgroup service is
available.
+ : @admins foo : ALL
User john and foo should get access from IPv6 host address.
+ : john foo : 2001:db8:0:101::1
User john should get access from IPv6 net/mask.
+ : john : 2001:db8:0:101::/64
Disallow console logins to all but the shutdown, sync and all other accounts, which are a member of the wheel group.
-:ALL EXCEPT (wheel) shutdown sync:LOCAL
All other users should be denied to get access from all sources.
- : ALL : ALL
