remove ??? in file, pls help ...

[hendnov]

Hi guys, just wondering about simple question.

I want to remove ??? in some of files. what I did is :

cp awi.xml awi.xml_tmp
cat awi.xml_tmp | sed s/???// > awi.xml

Is there any way to make it one way without copying to awi.xml_tmp first ?

coz I tried :

cat awi.xml | sed s/???// > awi.xml

the result it is the file awi.xml is blank (

any idea guys ??

 

[PHV]

And what about this ?
echo ",s/???//g\nw\nq" | ed -s awi.xml

Hope This Helps, PH.

Hi PHV,

Thanks for your reply, but

It didnt change anything yet
Here's what happened

adoc syducmp02 ~> echo ",s/???//g\nw\nq" | ed -s test
?
adoc syducmp02 ~>

and I checked test file, it doesn't change anything.

See your ed man page, perhaps the -s option is not available, i'd try it without that -s flag

Hi,

try rhis code

ex /path/to/yourfile 1>/dev/null 2>&1 <<- !EOEX
       1,$ s/???//g
       wq
!EOEX

include this code in a loop for other files

 

[PHV]

And this ?
echo "1,\$s/???//g\nw\nq" | ed -s test

Or this ?
/bin/echo echo "1,\$s/???//g\nw\nq" | ed -s test

Hope This Helps, PH.

What OS? Is sed -i available?

Annihilannic.

 

[Annihilannic]

Alternatively, perl -pi -e 's/\?\?\?//' awi.xml.

sed s/???// < awi.xml > awi.new

You should read the questions more carefully mrn, he wants to edit the file in place.

Annihilannic.

 

[mrn]

No he said he didn't want to copy it first, which is different to not creating a copy at all.

[Annihilannic]

Fair enough. I presume by "one way" though he meant in one step; using your method he would still have to copy awi.new back to awi.xml.

Annihilannic.

 

[mrn]

Hmmm I suppose you could be correct, but that's not how I read it. ok what about

sed s/???// < awi.xml > awi.new && mv awi.new awi.xml

[p5wizard]

Perhaps he wants to edit the file in place because some other process already has the file open and that process would need to be restarted otherwise? Just guessing...

[hendnov]

Hi Guys,

Thx for the input, yeah p5wizard is right.

I want to edit the file in place because this file is part of my application file. If I change it or copy it to another file first, I have to stop and restart the application. That's what I did in my staging server but in my production server which is online and has 4000 viewers, I can't just stop and restart the server.

That's all guys,

but I'll try mrn ways this morning, btw where are you guys from ??? I'm in Sydney ;p. Just wanna know you guys more. Coz you guys helped me alot. THX

 

[mrn]

Is the file being written to be the app? If it is I wouldn't mv the file.

UK - btw

[mrn]

You didn't answer Annihilannic do you have the -i option?

[hendnov]

Sorry guys,

I respond a little bit late, yeah my server didn't have sed -i option ( ?

Thx

 

[feherke]

Hi

That -i option would not help you anyway. It creates a new file.

I think your original solution is the best.
