Find information from complicated strings
Hi experts,

I have the file with these lines:
var1=thu_13:12:32,var2=Microsoft,var3=240ms,var4=Mozilla/4.0_(sun;_MSIR_3-4;_windows.;_NET_1.1323.53
var1=thu_13:13:32,var2=Microsoft,var3=213ms,var4=Mozilla/4.0_(sun;_MSIR_3-4;_windows.;_NET_1.1323.53
var1=thu_13:16:32,var2=Microsoft,var3=654ms,var4=Mozilla/4.0_(sun;_MSIR_3-4;_windows.;_NET_1.1xcv23.53


How can I transform it to:
thu_13:12:32,Microsoft,240ms,Mozilla/4.0_(sun;_MSIR_3-4;_windows.;_NET_1.1323.53
thu_13:13:32,Microsoft,213ms,Mozilla/4.0_(sun;_MSIR_3-4;_windows.;_NET_1.1323.53
thu_13:16:32,Microsoft,654ms,Mozilla/4.0_(sun;_MSIR_3-4;_windows.;_NET_1.1xcv23.53

Fundamentally, I would like to remove "XXXXX=".


Thank you

Thank you very much that helps
however,
There are some occasions that the equal sign can be inside a text.
var1=thu_13:12:32,var2=Microsoft,var3=240ms,var4=Mozilla/4.0_(sun;_MSIR_3-4;_reg=edit_windows.;_NET_1.1323.53)

so this one should give the result

thu_13:12:32,Microsoft,240ms,Mozilla/4.0_(sun;_MSIR_3-4;_reg=edit_windows.;_NET_1.1323.53)

assuming your naming convention is var1,var2..var9 then:

Code:
 sed 's/var.=//g' infile
should be sufficient if i've read your question correctly

Friend you had seen how to replace a pattern using sed and awk, try to find a common pattern for the string to be replaced for Eg:
echo $var |awk '{gsub(",....=",",");print}'
this will replace ,xxxx= with ,
