UNIX script to compare 3rd column value with first column and display
Thank you so much, above code is working fine.
I have question, in first column value is same for two or more columns then in out put is skipping duplicate rows
Now my input is like below:
Expecting output like

Here is my situation. I need to compare two tab separated files (diff is not useful since there could be known difference between files).
I have found similar posts , but not fully matching.I was thinking of writing a shell script using cut and grep and while loop but after going thru posts it... (2 Replies)
Hi,
I am writing a comparator script, which comapre two txt files(column by column)
below are the precondition of this comparator
1)columns of file are not seperated
Ex.
file1.txt

1243548895685687
8945896789897789

Hi,
I need an awk script (or whatever shell-construct) that would take data like below and get the max value of 3 column, when grouping by the 1st column.
clientname,day-of-month,max-users

client1,20120610,5
client2,20120610,2

Hi, I have a file with +/- 13000 lines and 4 column. I need to search the 3rd column for a word that begins with "SAP-" and move/skip it to the next column (4th). Because the 3rd column need to stay empty.
Thanks in advance.:)
89653 36891 OTR-60 SAP-2
89653 36892 OTR-10 SAP-2... (2 Replies)
Input file :
5 20
500 2
20 41
41 0
23 1
Desired output :
5
2
20
0
1
By comparing column 1 and 2 in each line, I hope can print out the column with smallest number.
I did try the following code, but it don't look good :( (2 Replies)
I have the following 2 files.
File 1

"S", T","U,V","U,V","X"
"AA","BB","CC,DD","CC,DD","FFF"
tried using awk but double quotes not preserving for every field. any help to solve this is much... (5 Replies)
Example:
I have files in below format
file 1:
zxc,133,joe@example.com
cst,222,xyz@example1.com
File 2 Contains:
hxd
hcd
jws
zxc
cst
File 1 has 50000 lines and file 2 has around 30000 lines :
Expected Output has to be :
hxd
hcd

rtsol
RTSOLD(8) BSD System Manager's Manual RTSOLD(8)NAME
rtsold -- router solicitation daemon
SYNOPSIS
rtsold [-dDfm1] interface ...
rtsold [-dDfm1] -a
rtsol [-dD] interface ...
rtsol [-dD] -a
DESCRIPTION
rtsold is the daemon program to send ICMPv6 Router Solicitation messages on the specified interfaces. If a node (re)attaches to a link,
rtsold sends some Router Solicitations on the link destined to the link-local scope all-routers multicast address to discover new routers and
to get non link-local addresses.
rtsold should be used on IPv6 hosts (non-router nodes) only.
If you invoke the program as rtsol, it will transmit probes from the specified interface, without becoming a daemon. In other words, rtsol
behaves as ``rtsold -f1 interfaces''.
Specifically, rtsold sends at most 3 Router Solicitations on an interface after one of the following events:
o Just after invocation of rtsold daemon.
o The interface is up after a temporary interface failure. rtsold detects such failures by periodically probing to see if the status of
the interface is active or not. Note that some network cards and drivers do not allow the extraction of link state. In such cases,
rtsold cannot detect the change of the interface status.
o Every 60 seconds if the -m option is specified and the rtsold daemon cannot get the interface status. This feature does not conform to
the IPv6 neighbor discovery specification, but is provided for mobile stations. The default interval for router advertisements, which is
on the order of 10 minutes, is slightly long for mobile stations. This feature is provided for such stations so that they can find new
routers as soon as possible when they attach to another link.
Once rtsold has sent a Router Solicitation, and has received a valid Router Advertisement, it refrains from sending additional solicitations
on that interface, until the next time one of the above events occurs.
When sending a Router Solicitation on an interface, rtsold includes a Source Link-layer address option if the interface has a link-layer
address.
Upon receipt of signal SIGUSR1, rtsold will dump the current internal state into /var/run/rtsold.dump.
OPTIONS -a Autoprobe outgoing interface. rtsold will try to find a non-loopback, non-point-to-point, IPv6-capable interface. If rtsold finds
multiple interfaces, rtsold will exit with error.
-d Enable debugging.
-D Enable more debugging including the printing of internal timer information.
-f-f prevents rtsold from becoming a daemon (foreground mode). Warning messages are generated to standard error instead of syslog(3).
-m Enable mobility support. If this option is specified, rtsold sends probing packets to default routers that have advertised Router
Advertisements when the node (re)attaches to an interface. Moreover, if the option is specified, rtsold periodically sends Router
Solicitation on an interface that does not support SIOCGIFMEDIA ioctl.
-1 Perform only one probe. Transmit Router Solicitation packets until at least one valid Router Advertisement packet has arrived on
each interface, then exit.
DIAGNOSTICS
The rtsold utility exits 0 on success, and >0 if an error occurs.
FILES
/var/run/rtsold.pid the pid of the currently running rtsold.
/var/run/rtsold.dump dumps internal state on.
SEE ALSO rtadvd(8), sysctl(8)HISTORY
The rtsold command is based on the rtsol command, which first appeared in WIDE/KAME IPv6 protocol stack kit. rtsol is now integrated into
rtsold(8).
BUGS
In some operating systems, when a PCMCIA network card is removed and reinserted, the corresponding interface index is changed. However,
rtsold assumes such changes will not occur, and always uses the index that it got at invocation. As a result, rtsold may not work if you
reinsert a network card. In such a case, rtsold should be killed and restarted.
The IPv6 autoconfiguration specification assumes a single-interface host. You may see kernel error messages if you try to autoconfigure a
host with multiple interfaces. Also, it seems contradictory for rtsold to accept multiple interface arguments.
