Reading and appending a row from file1 to file2 using awk or sed
Hi, I wanted to add each row of file2.txt to entire length of file1.txt given the sample data below and save it as new file. Any idea how to efficiently do it. Thank you for any help.
I have an Awk string-compare problem and have searched the internet and forums for a solution i could use but cannot find a solution i understand to make work with my particular problem:
I need to compare (field1 field2 field3 of File1) against (field1 of File2) and if they match print out... (6 Replies)
I'm trying to compare two files using AWK, where if field2 of both files match, replace field1 of file1 with field1 of file2 and if there is no match just print the line of file1.

Hi All,
as you can see I'm pretty new to this board. :D
I'm struggling around with small script to search a few fields in another file.
Basically I have file1 looking like this:

15:38:28 sz:10002 pr:18.41
15:38:29 sz:10003 pr:19.28

I have very limited coding skills but I'm wondering if someone could help me with this. There are many threads about matching strings in two files, but I have no idea how to add a column from one file to another based on a matching string.
I'm looking to match column1 in file1 to the number... (3 Replies)

My original files are like this below and I distinguish them from the AP_ID (file1 has 572 and file2 has 544). Also, the header on file1 has “G_” pre-pended. NOTE: these are only snippets of very large files and much of the data is not present here.

I am trying to use awk to find all the $2 values in file2 which is ~30MB and tab-delimited, that are between $2 and $3 in file1 which is ~2GB and tab-delimited.
I have just found out that I need to use $1 and $2 and $3 from file1 and $1 and $2of file2 must match $1 of file1 and be in the range... (6 Replies)
Trying to use awk to:
update $2 in file2 with the $2 value in file1, if $1 in file1 matches $13 in file2, which is tab-delimeted. The $2values may already be the same so in that case nothing happens and the next line is processed.
There are exactly 4,605 unique $13 values. Thank you :).

This is a question that is related to one I had last August when I was trying to sort/merge two files by millsecond time column (in this case column 6).
The script (below) that helped me last august by RudiC solved the puzzle of sorting/merging two files by time, except it gets lost when the... (0 Replies)

LEARN ABOUT FREEBSD
rndtest
RNDTEST(4) BSD Kernel Interfaces Manual RNDTEST(4)NAME
rndtest -- FIPS 140-2 random number generator test monitor
SYNOPSIS
device rndtest
DESCRIPTION
The rndtest driver ``hooks up'' to hardware crypto devices to monitor the entropy data passed to the random(4) subsystem. This data is peri-
odically tested for FIPS 140-2 compliance and statistics are collected. If the harvested entropy fails any of the FIPS test suite, then it
is discarded and testing is continuously applied until ``good data'' is received from the device. Failures are optionally reported on the
console.
SEE ALSO crypto(4), hifn(4), random(4), safe(4), ubsec(4), crypto(9)HISTORY
The idea for this and the original code came from Jason L. Wright. The rndtest device driver first appeared in FreeBSD 5.0.
BUGS
Crypto device drivers must be compiled specially to make use of this driver; this should not be necessary. This feature might better be
integrated into the random(4) subsystem where it can be applied to devices that claim to supply ``pure entropy''.
