Dear experts,

I have many files containing a line as below:

GPEHDownloadAll = "0"

I want to change this line in these files to:

GPEHDownloadAll = "0" ----> GPEHDownloadAll = "1"  (zeros will be one)

Note: Be careful of spaces between equal sign.

Can you help me using sed for this?

BR,

sed  's/GPEHDownloadAll = "0"/GPEHDownloadAll = "1"/' inputfile

Or is there not always the same number of spaces?

Sorry, I just saw "many files"

grep -l 'GPEHDownloadAll = "0"' * | xargs -I{} sed  -i 's/GPEHDownloadAll = "0"/GPEHDownloadAll = "1"/' {}

Attention - the above will change the files "in place"!
