sed search and replace

Jannik — Tue, 19 Aug 2008 06:55:51 GMT

I have been looking for a solution for this, but can't find one.

I have a lot of .html files that i need to edit though crontab.

This is the string I am looking for:
src="*../something/styleAssets.somthing.something*"
src='*../something/styleAssets.somthing.something*'
href="*../something/styleAssets.somthing.something*"
href='*../something/styleAssets.somthing.something*'

to be replaced with a string:
http:/mydomain.com/styleAssets

I were thinking of something like this:

for i in $(find /www/myDir -type f -name '*.html')
do
sed -e 's/styleAssets/http:\/\/mydomain.com\/styleAssets/g' $i > $i.new
cp $i.nw $i
done

But that is not correct since i need to replace all within the single or double quote.

tnx.

It would help if you provided a line or 2 of the actual text which included the string(s) you want to replace.

Shalom,

Try using escape characters.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

menu

And only if the reference hold the text styleAssets to begin with.

Try these:
sed -e 's;".*/styleAssets\..*\..*\..*";"http://mydomain.com/styleAssets";g' \
-e "s;'.*/styleAssets\\..*\\..*\\..*';'http://mydomain.com/styleAssets';g" \
$i

I have some of the solution...

Input file:

Perl script href.pl:
s/href=(["'][^"']+["'])/href=\"http:\/\/mydomain.com\/styleAssets\"/ig

Perl script src.pl:
s/src=(["'][^"']+["'])/src=\"http:\/\/mydomain.com\/styleAssets\"/ig

The run script:
for i in $(find ./ -type f -name '*.html')
do
perl -p -i.old1 href.pl $i
perl -p -i.old2 scr.pl $i
done

But this solution also change lines witch does not hold a reference to styleAssets.

I need some "if" statement in the perl script.

Hi:

# perl -pi.old -e 's{((src|href)=")\.\..([^"]+")}{$1http:/mydomain.com/$2}' file

...which also preserves the original file as "file.old".

Hey Dennis your does not seem to work.
Hey James your perl works partly except that it changes everything between the quotes even if it does not hold the word styleAssets.

I'm trying to make the changes but it seems that I need some help with that.

Hi (again) Jannik:

> Hey James your perl works partly except that it changes everything between the quotes even if it does not hold the word styleAssets.

Oops, sorry about that.

# perl -pi.old -e 's{((?:src|href)=")\.\.(/styleAssets[^"])}{$1http:/mydomain.com$2}' file

Regards!

I will keep the tread open; if somebody find a better solution or a sed solution that works please post it.

I will try to work on the post from Kevin.

>Hey Dennis your does not seem to work.

Because I was matching the explicit "." you had.

Try this, it uses the [^"] trick:

sed -e 's;".*/styleAssets/[^"]*";"http://mydomain.com/styleAssets";' \
-e "s;'.*/styleAssets/[^']*';'http://mydomain.com/styleAssets';" $i
