sed script work, oneliner not work, what's the problem?

[will27]

Hi, all
suppose I have following txt file "people"

Tim US
Xue CHN
Will US
Tom US
Yong CHN

if I work with a sedscript as following:

/US$/ {
s//USA/
w us.origin_1
}

then following code works

 sed -n -f sedscript people

However, its oneliner version as below doesn't

sed '/US$/ {s//USA/; w us.origin_1}' people

the error message is:
sed: -e expression #1, char 0: Unmatched `{'

How should I deal with this message?

Thank you

Regards
will

Hi

In some cases [tt]sed[/tt] counts on the presence of newline characters :

sed '/US$/ {s//USA/; w us.origin_1
}' people

[gray]# or[/gray]

sed '/US$/ s//USA/; /USA$/ w us.origin_1' people

What about this ?
sed '/US$/{;s//USA/;w us.origin_1;}' people

Hope This Helps, PH.

Hi

At least GNU [tt]sed[/tt] does not accept it. The semicolon ( ; ) can be part of a filename, so can not delimit it.

OOps, the w command should be terminated with EOF or EOL.

Hi,
thanks,
PHV and feherke.
I do agree with feherke that the this thread is somewhat off-topic, I assume people who has expertise on awk will also be familiar with sed.
Anyway, the task can be pretty decently done with awk.

Best

Hi

I agree, that is mostly correct.

The reason for choosing the most appropriate forum is not us, but those who will come later and will search the forum archive for similar problem.
