Hey cfa!

Code:
string=${string// /%20}

This ended up working in Mac OS X but not in ubuntu hardy, I was getting an error so I ended up using vid's solution:

Code:
series_name=`echo "$series_name"|sed 's/ /%20/g'`

This works just fine on ubuntu hardy.

Do you know a lot about sed? I used vid's solution for extracting a number in between <seriesid></seriesid> in an xml file and it worked fine in Mac OS X but when I tried it in ubuntu hardy the output is blank, no number, nothing.

mind taking a look? Here is the sample XML

Code:
<Data>
−
<Series>
<seriesid>73545</seriesid>
<language>en</language>
<SeriesName>Battlestar Galactica (2003)</SeriesName>
<banner>graphical/73545-g11.jpg</banner>
−
<Overview>blah blah blah blah</Overview>
<FirstAired>2003-12-01</FirstAired>
<IMDB_ID>tt0407362</IMDB_ID>
<zap2it_id>SH710749</zap2it_id>
<id>73545</id>
</Series>
</Data>

and here is the solution given to me by vid to extract "73545" and set it to a variable

Code:
variable=`sed -ne 's/\(^\<seriesid\>\)\(.*\)\(\<\/seriesid\>\)/\2/p' filename|head -1`
