ECHO LINES TO A BLANK
To echo all lines in a
file upto the first blank
line use the following:
awk '$0 ~ /^$/ {exit;} {print $0;}' <file_name>
The awk script can be used
for printing lines upto the
first occurence of any
pattern.
Just substitute ^$ with
the pattern.
I wrote this script to parse
http server headers.

Unix Tip: FTP AUTOMATED TRANSFERS

http://www.ugu.com/sui/ugu/show?tip.today

FTP AUTOMATED TRANSFERS
To add to the earlier tip
on automated transfer using
FTP, you can define a macro
by name 'init' which will
automate the whole transfer.
Defining the macro.
In the .netrc file after the
definition for the machine
name,add the following
definition.
macdef init
bin
hash
cd <directory>
!cd <directory>
put/get <filename>
bye
The line begining with macdef
starts the definition of a
macro.All the sub sequent
lines upto a blank line (or
end of file) are part of
the macro.
Now if you type ftp
<machine name> at the prompt,
the whole ftp will happen
automatically.
These macros can also be
defined in any other name in
which case,you will have to
type the macro name at the
ftp prompt for its statements
to get executed.

AUTOMATIC LOGIN TO REMOTE HOSTS
Consider two hosts.
host1.domain.com
host2.domain.com
>From hosts(user:deepak),
you wish to logon to
host1(user:paul).
Paul would create a .rhosts
file in his directory
chmod 744 .rhosts
(No write permission for
others) The first line
would contain
host1.domain.com deepak
Now, deepak should be able
to logon to host2.domain.com
as user paul by using rlogin.
Deepak will type
e.g
rlogin hosts.domain.com -l paul
And he should be in.

Unix Tip: LARGES FILES MORE FLAVORS

UNIX GURU UNIVERSE
UNIX HOT TIP
Unix Tip 3425 - June 25, 2012
http://www.ugu.com/sui/ugu/show?tip.today

LARGES FILES MORE FLAVORS
Recently a single line
script was posted to UGU
to list the largest files
in a filesystem in order
of descending size.
The script worked as posted
on AIX but required tweaking
for SCO OSR5 and UW7.
Here 'tis for your
edification and enjoyment:
OSR5:
find $1 -type f -size +2048 -xdev -exec ls -s {} | /bin/sort -brut " "
UW7:
find $1 -type f -size +2048 -xdev -exec ls -s {} + | /bin/sort -nr
I placed the script in
/usr/local/bin and removed
the pipe to "more" in the
published version to allow
redirection to a file. I
also arbitrarily added the
"-size +2048" to the find
command to limit the list
to files of 1 Mb or larger;
you may modify or remove as
desired.
Thank you,
Lucky Leavell
