sed: 1: &quot;s\^t*<logs>\(.*\)<\/log ...&quot;: substitute pattern can not be delimited by newline or backslash






fbsd# cat AirseServer.xml | grep &quot;<logs>&quot; | sed -e 's\^\t*<logs>\(.*\)<\/logs>!\1!'


sed: 1: &quot;s\^t*<logs>\(.*\)<\/log ...&quot;: substitute pattern can not be delimited by newline or backslash

Hi,
Can you run the file through

expand

This will by default expand all tabs to a tabstop of 8 spaces. if you want smaller tabs stops you can specify that as well.

then you can just do something like

s/ */ /g

which will substitute every group of 2 or more spaces to a single space.

unfortunately this doesn't know about quotes or strings and therefore may remove spaces in Strings altering the contents of tags.

Is \t == <tab> at here ?

 

[dickiebird]

to delete all tabs :-
sed 's/'`echo &quot;\015&quot;`'//g' file > filenew

it seems echo &quot;\015&quot; donot work

 

[dickiebird]

The only way I could get this to work myself was :
sed 's/ //g' dumfile > newfile
where this gap after &quot;s/&quot; is created by holding down Cntrl V and pressing capital I ( which creates a tab )

Are you sure you're using backticks here:

sed 's/'`echo &quot;\015&quot;`'//g' file > filenew

Backticks can usually be found above the tab key, below Esc.

HTH.
