Hello Friends,
i used awk to sum up total size of files under a directory (with the help of examples, threads here).
ls -l | awk '/^-/ {total += $5} END {printf "%15.0f\n",total}' >> total.txt
After each execution of the script total result is appended into a text file:
7010
7794
8890 ... (7 Replies)
I have a txt file as follows
Code:
Oct 1 file1 4144
Oct 1 file23 5170
Oct 2 file5 3434
Oct 21 file56 2343
I need to add a new column by marking the right log file from current directory. For example populate like this. Please not in the second columt for "1" it has... (2 Replies)
Is there anyway to use awk to add a first column to my data that automatically goes from 1 to n , where n is the numbers of my rows?:confused: (4 Replies)
Hello everyone,
I have a file with the following structure:
abc xyz 111 222
agf hjhf 787 799
tht yah 878 898
... ... ... ...
... ... ... ...
... ... ... ...
I want to add a column (with a fixed value of 1000) at the end such that it becomes:

Hi,
test.txt contains below values
1
2
3
4
5
Desired output:
'TT.1',
'TT.2',
'TT.3',
'TT.4',
'TT.5'
Last value should not contain the comma after the value. Below is the script which i have tried. I'm using Linux.
#!/bin/bash
for i in $test.txt (4 Replies)
Hi ,
Can any one please tell me, how can we add the file name as column using sed.
right now we are using the below awk command for adding the file name as column but when we are calling this script from datastage it is deleting the file data..very weird raised a support ticket with datastage.... (2 Replies)
Hi everyone!
I sometimes need to do some simple arithmetics, like adding a number to a certain column of a file. So I wrote a small function in the .bashrc file, which looks like this
shifter()
{
COL=$1
VAL=$2
FILE=$3
cp $FILE $FILE.shifted
awk 'NF==4 {$(( $COL )) = $(( $COL ))... (6 Replies)
Hello
Im new treat me nicely, I have a headache :)
I have a script that seemed to work now it doesnt anyway, the last part is adding counts of unique items in a csv file eg
05492U34 38
05492U34 47
two columns, (many different values like this in file)
i want... (7 Replies)
I need the use sed or AWK using cat the file

INTRO(4) Kernel Interfaces Manual INTRO(4)NAME
intro - introduction to special files and hardware support
DESCRIPTION
This section describes the special files, related driver functions, and networking support available in the system. In this part of the
manual, the SYNOPSIS section of each configurable device gives a sample specification for use in constructing a system description for the
/sys/conf/configscript, the autoconfig(8), program and descibes the major and minor device numbers and their encoding. The DIAGNOSTICS
section lists messages which may appear on the console and/or in the system error log /usr/adm/messages due to errors in device operation.
This section contains both devices which may be configured into the system, ``4'' entries, and network related information, ``4N'', ``4P'',
and ``4F'' entries; The networking support is introduced in intro(4N).
PDP DEVICE SUPPORT
This section describes the hardware supported on the DEC PDP-11. Software support for these devices comes in two forms. A hardware device
may be supported with a character or block device driver, or it may be used within the networking subsystem and have a network interface
driver. Block and character devices are accessed through files in the file system of a special type; c.f. mknod(8). Network interfaces
are indirectly accessed through the interprocess communication facilities provided by the system; see socket(2).
A hardware device is identified to the system at configuration time and the appropriate device or network interface driver is then compiled
into the system. When the resultant system is booted, the autoconfiguration facilities in the system probe for the device on either the
UNIBUS (or Q-bus) or MASSBUS and, if found, enable the software support for it. If a device does not respond at autoconfiguration time it
is not accessible at any time afterwards. To enable a device which did not autoconfigure, the system will have to be rebooted.
The autoconfiguration system is described in autoconfig(8). A list of the supported devices is given below.
SEE ALSO intro(4), networking(4), config(8).
LIST OF DEVICES
The devices listed below are supported in this incarnation of the system. Pseudo-devices are not listed. Listed also are devices which
are in various stages of porting to 2.11BSD from 4.3BSD.
Devices are indicated by their functional interface. If second vendor products provide functionally identical interfaces they should be
usable with the supplied software. (Beware, however, that we promise the software works ONLY with the hardware indicated on the appropri-
ate manual page.) Occasionally, new devices of a similar type may be added simply by creating appropriate table entries in the driver.
The following are known to work:
acc ACC LH/DH IMP communications interface
de DEC DEUNA 10Mb/s Ethernet controller
dh DH-11 emulators, terminal multiplexor
dhu DHU-11 terminal multiplexor
dz DZ-11 terminal multiplexor
ec 3Com 10Mb/s Ethernet controller
hk RK6-11/RK06 and RK07 moving head disk
ht TM03 MASSBUS tape drive interface (with TE-16, TU-45, TU-77)
il Interlan 1010, 1010A, 2010A 10Mb/s Ethernet controller
lp LP-11 parallel line printer interface
qe DEC DEQNA Q-bus 10 Mb/s Ethernet interface
ra DEC UDA-50, RQDX, KLESI disk controllers
rk DEC RK05 disk controller
rl DEC RL-11 disk controller
rx DEC RX02 floppy interface
si SI 9500 disk controller
tm TM-11/TE-10 tape drive interface
tmscp TMSCP-compatible tape controllers (e.g., TU81, TK50)
ts TS-11 tape drive interface
vv Proteon proNET 10Mb/s and 80Mb/s ring network interface
xp General purpose SMD disk controller
The following should work:
dr DR-11W general purpose DMA UNIBUS interface
The following worked in the past but will probably require work:
css DEC IMP-11A communications interface
dmc DEC DMC-11/DMR-11 point-to-point communications device
en Xerox 3Mb/s Ethernet controller (obsolete)
sri DR-11C IMP interface
It should be possible to port these from 4.3BSD:
ex Excelan 10Mb/s Ethernet controller
ix Interlan NP-100 10Mb/s Ethernet controller
np Interlan NP-100 10Mb/s Ethernet controller (intelligent mode)
pcl DEC PCL-11 communications interface
No idea whether any of the following could be ported:
ad Data translation A/D interface
ct C/A/T or APS phototypesetter
ddn ACC ACP625 DDN Standard Mode X.25 IMP interface
dmf DEC DMF-32 terminal multiplexor and parallel printer interface
dmz DEC DMZ-32 terminal multiplexor
dn DEC DN-11 autodialer interface
hdh ACC IF-11/HDH IMP interface
hp MASSBUS disk interface (with RP06, RM03, RM05, etc.)
