Hi all

I have this sed command that works find on the command line but when i call it from a perl script is errors

Code

sed: -e expression #1, char 41: unknown command: `<'

Please show how you call it from Perl. I can't answer without that.

But the main point is that there is no point calling a sed command from Perl, since Perl can do everything that sed can do, and it can do it better and il most cases faster. You should do it in Perl.

this is my code

Code

my $searchterm=`defaults read /Users/$USER/Library/Preferences/com.apple.iChat.Jabber.plist | grep -w "AllowClearTextPasswords = 1"`; 
if ( $? !=0 ) { 
        _log("Converting com.apple.iChat.Jabber.plist to xml "); 
        system("plutil -convert xml1 /Users/$USER/Library/Preferences/com.apple.iChat.Jabber.plist"); 
        _log("Adding in the correct line"); 
        my $cmd = "/apps/MacOS/ports/10.8/libexec/gnubin/sed -i '13 i <key>AllowClearTextPasswords</key>\n<true/>' /Users/$USER/Library/Preferences/com.apple.iChat.Jabber.plist";
