sed !!1
 

hi
i am using sed to make dynamic cnages on the fly in one of my log files.

the org log file looks like this:

RETR "RETR account.cfm" /root/http/myfiles/account.cfm


& i am trying to change this line to:

get account.cfm



how do i do that ? is it possible using sed or do i need to use awk?

waiting ur all responses.

assuming that account.cfm is always in the 3rd position...
awk '{print "get " $3}' logfilename | sed 's/.$//g'

You could probably do it all with sed but awk was a little easier to make it just grab the 3rd field...

hi blinker ...
 

hello ..

thnks for replying,,, i tried as u said but it adds the "get" on all the lines of the log file , what i want is "get" should be added only on the line which lloks like this:

RETR "RETR hello.cfm" /root/home/test/hello.cfm


& i want only such lines which start with a RETR to be changed to:


get hello.cfm

etc...


hope u understand what i mean.

thanks & waiting for ur reply

Sorry had a brain fart... ;)
try this...
grep RETR LOGFILENAME | awk '{print "get " $3}' | sed 's/.$//g'

Hold on that will just get the RETR lines... thinking give me a sec... ;)

Quick question are you only looking for files named .cfm and will the /root/http... always be what you want removed? cause if you are something like:
sed 's/RETR..RETR/get/g' FILENAME | sed 's/cfm.*root*/cfm/'
Might do the job...

hi again
 

it works fine by replacing the line that starts with RETR with get <filename> ...

but theres a problem , rest of the lines of the log file are washed away, but i dont want that. i want the rest of thelines to be the same as they were & only the line that starts with RETR should be changed to get <filename>

thnks again

How about some sample lines? like some lines that are similar that you want left in the log file?

my org log file looks like this for ex:

USER "USER test4"
PASS "PASS test4"
CWD myfiles "CWD myfiles"
RETR "RETR welcome.cfm" /root/http/myfiles/welcome.cfm
STOR "STOR email.cfm" /root/http/myfiles/email.cfm
RETR "RETR hello.cfm" /root/home/test/hello.cfm
RNFR "RNFR old.cfm" /root/songs/old.cfm
RNTO "RNTO new.cfm"


i was also wondering how could I change the STOR & RNFR & RNTO lines in the above log file to :

USER "USER test4"
PASS "PASS test4"
CWD myfiles "CWD myfiles"
get welcome.cfm
put /root/http/myfiles/email.cfm email.cfm
get hello.cfm
rename /root/songs/old.cfm new.cfm


this is how i want my log file to be changed,ie

1) RETR --> get <filename>
2) STOR --> put /URL/<filename> <filename>
3) RNFR & RNTO ---> rename /URL/<oldfilename> <newfilename>


i hope u know what i mean ....




so i want the abov

***sorry posted while you were... *** ignore this... ;)

sed -r 's/RETR..RETR.*.myfiles./get/g' LOGFILE

here's one that looks the RETR and the myfiles (WARNING If myfiles is not there this one won't change anything!)

here's my junk file for testing:
RETR "RETR account.cfm" /root/http/myfiles/account.cfm
RETR "RETR account3.cfm" /root/http/myfiles/account.cfm
RETR "RETR account2.cfm" /root/http/myfiles/account.cfm
RETR "RETR account1.cfm" /root/http/myfiles/account.cfm
account1.cfm" /root/http/myfiles/account.cfm
account1.cfm" /root/http/myfiles/account.cfm
ETR account1.cfm" /root/http/myfiles/account.cfm
count1.cfm" /root/http/myfiles/account.cfm
test test.cfm test test
test test.cfm test test
test test test test
test.cfm test test test
test test test test.cfm

and after I run sed -r 's/RETR..RETR.*.myfiles./get/g' LOGFILE
getaccount.cfm
getaccount.cfm
getaccount.cfm
getaccount.cfm
account1.cfm" /root/http/myfiles/account.cfm
account1.cfm" /root/http/myfiles/account.cfm
ETR account1.cfm" /root/http/myfiles/account.cfm
count1.cfm" /root/http/myfiles/account.cfm
test test.cfm test test
test test.cfm test test
test test test test
test.cfm test test test
test test test test.cfm

did u read my prev mail |?

waiting for ur reply?

thanks

sorry went to lunch... ;) little fried rice and some sweet and sour chicken :D:D:D
Think I finally figured out the RETR one... the other 2 should be similar...

sed 's/RETR..RETR/get/g' FILENAME | sed 's/get.*cfm./&blinkerfluid/g' | sed 's/.blinkerfluid.*//g'

The mother of all sed commands!

sed 's/RETR..RETR/get/g' FILENAME | sed 's/get.*cfm./&blinkerfluid/g' | sed 's/.blinkerfluid.*//g' | sed 's/STOR..STOR\(.*\) \(.*\)/get \2 \1/g' |sed 's/RNTO..RNTO\(.*\) \(.*\)/rename \2 \1/g' | sed 's/RNFR..RNFR\(.*\) \(.*\)/rename \2 \1/g'| sed 's/cfm.$/cfm/'

k so I learned a few shortcuts with the later commands... ;) I think you can also use some other command like a -e instead of piping but I'll have to look into it more...

one item that you may want to think about the RNTO line was originally:
RNTO "RNTO new.cfm"
and you wanted it changed to rename? Might want to look at that one because there isn't a path after...

what does the " &blinkerfluid " do ?

The & sign basically takes the expression you looked for and dumps it back in. the Blinkerfluid is just something I bet you don't have in your file that I would search on to eliminate that pesky " mark.

i am not specific to only .cfm files it can be anything, say a .txt, .bin or any other file?

Oh sure ;)
Give me a minute...
