Hi guys,
I'm rather new at using UNIX based systems, and when it comes to scripting etc I'm even newer.
I have two files which i need to compare.
file1: (some random ID's)
451245
451288
136588
784522
file2: (random ID's + e-mail assigned to ID)

Dear Gurus,
I am very new to UNIX. I appreciate your help to manage my files.
I have 16 files with equal number of columns in it. Each file has 9 columns separated by space. I need to compare the values in the second column of first file and obtain the corresponding value in the 9th column... (12 Replies)
I have two text files where the first three columns are exactly the same. I want to compare the fourth column of the text files and if the values are different, print that row into a new output file. How do I go about doing that?
File 1:
100 rs3794811 0.01 0.3434
100 rs8066551 0.01... (8 Replies)
Hi,
I have two text files with matching first columns. Some of the values in the second column do not match. I want to write a script to print out the rows (only the first column) where the values in the second column do not match.
Example:
Input 1
A 1
B 2
C 3
D 4
Input 2
A 2
B 2... (6 Replies)
Hi , I want to compare first 3 columns of File A and File B and create a new file File C which will have all rows from File B and will include rows that are present in File A and not in File B based on First 3 column comparison.
Thanks in advance for your help.

Hi all, I'm trying to match the following two files with the code below:
awk -F, 'NR==FNR {a=$0; next} ($12,$4) in a {print $12,$1,a}' OFS="," file4.csv file3.csv
but the code does not print the entire row from file4 in addition to column 12 and 1 of file3.
file4:

Hi,
i have 2 files , the data i need to match is in masterfile and i need to pull out column 3 from master if column 1 and 2 match and output entire row to new file

vlan
VLAN(4) BSD Kernel Interfaces Manual VLAN(4)NAME
vlan -- IEEE 802.1Q Virtual LAN network device
SYNOPSIS
pseudo-device vlan
DESCRIPTION
The vlan interface provides support for IEEE 802.1Q Virtual Local Area Networks (VLAN). This supports the trunking of more than one network
on a single network interface. This is particularly useful on routers or on hosts which must be connected to many different networks through
a single physical interface.
To use a vlan interface, the administrator must first create the interface and then specify the VID (VLAN identifier, the first 12 bits from
a 16-bit integer which distinguishes each VLAN from any others) and physical interface associated with the VLAN. This can be done by using
the ifconfig(8) create, vlan, and vlanif subcommands from a shell command line or script. From within a C program, use the ioctl(2) system
call with the SIOCSIFCREATE and SIOCSIFVLAN arguments.
To be compatible with other IEEE 802.1Q devices, the vlan interface supports a 1500 byte MTU, which means that the parent interface will have
to handle packets that are 4 bytes larger than the original Ethernet standard. Drivers supporting this increased MTU are:
- drivers using the DP8390 core (such as ec(4), ne(4), we(4), and possibly others)
- bge(4)
- bnx(4)
- ea(4)
- eb(4)
- epic(4)
- etherip(4)
- ex(4)
- fxp(4)
- gem(4)
- hme(4)
- le(4)
- sip(4)
- ste(4)
- stge(4)
- ti(4)
- tl(4)
- tlp(4)
- vge(4)
- vr(4)
- wm(4)
- xi(4)
vlan can be used with devices not supporting the IEEE 802.1Q MTU, but then the MTU of the vlan interface will be 4 bytes too small and will
not interoperate properly with other IEEE 802.1Q devices, unless the MTU of the other hosts on the VLAN are also lowered to match.
EXAMPLES
The following will create interface vlan0 with VID six, on the Ethernet interface tlp0:
ifconfig vlan0 create
ifconfig vlan0 vlan 6 vlanif tlp0
After this set up, IP addresses (and/or other protocols) can be assigned to the vlan0 interface. All other hosts on the Ethernet connected
to tlp0 which configure a VLAN and use VID six will see all traffic transmitted through vlan0.
The same VLAN can be created at system startup time by placing the following in /etc/ifconfig.vlan0:
create
vlan 6 vlanif tlp0
SEE ALSO ifconfig(8)HISTORY
The vlan device first appeared in NetBSD 1.5.1, and was derived from a VLAN implementation that appeared in FreeBSD and OpenBSD.
BUGS
The vlan interfaces do not currently inherit changes made to the physical interfaces' MTU.
