File:12345.JPG

I have a file which has numbers at the start of some of the lines.

Code: aaa aaa   1 aaa  bbb  ccc  ddd 12345  12345   2 aaa  bbb  ccc  ddd 12345  12345   3 aaa  bbb  ccc  ddd 12345  12345   4 aaa  bbb  ccc  ddd 12345  12345

bbb   5 aaa  bbb  ccc  d

My simple understanding of NAT is something like this could happen:

Two client PCs 192.168.1.2 and 192.168.1.3 open up a connection with src port = 12345.

Hi All,

I have a file like this

red 12345 12345 abc red ddd red dfgd abc blue 123 123 red123 123red123

I need to comment all lines from this file containing the string 'red'. Desired output.

#red 12345 #12345 abc red #ddd red dfgd abc blue 123 #123 red123 #123red123

How to achive this in Unix?? Thanks, sarin

I was looking for the difference between the "." and "source" builtin commands and a few sources (e.g., in this discussion, and the bash manpage) suggest that these are just the same.

However, following a problem with environment variables, I conducted a test.

I intalled opendkim with sendmanil (on Ubuntu) without any problem, and followed the same procedure for installing on another server (Debian with postfix), but it does not work. Strangely, there is no error in the log files too.

I have this following file:-

$ cat numbers a1 12 12345 123456 19816282 1@$%6

I am using grep "^[0-9]\{1,6\}$" numbers which is giving me the following results:-

12 12345

I was expecting 1@$%6 also in the results. Please correct me if I am wrong?

Apologies for the confusing question title, but I'm not exactly sure how to describe the issue at hand.

I have two tables in Oracle 9i:

Pricing ------- SKU ApplicableTime CostPerUnit

Inventory --------- SKU LastUpdatedTime NumberOfUnits

Pricing contains incremental updates to the costs of each particular SKU item, at a specific Unix time.

In a GNU/Linux OS there is no way to change ownership of a file until you are root. But what if I want to hide my system’s username e.g. before sending a file to someone, because some things like tar will try to keep it?

What I think about is something like

# mkdir --mode=?????

Hello, I have two source files:

sourcefile1.dat:

Code: 12345 xxx yyy zzz 23456 qqq ttt rrr 34567 ppp jjj ggg 45678 fff ddd sss 56789 nnn mmm ccc sourcefile2.dat:

Code: 12345.gif 34567.gif I want to obtain a simple awk one linger to obtain the following:
