Bash Commands in root

ROOT
1

Hello

I would like to ask, if is possible to use bash commands implemented in a macro …

For example , I would like to use awk to read the header of a text file, which I want to save in a root tree – ie, using the bash syntax

[code]double mass[2];

awk ‘BEGIN{FS="&&"}/&&/{ print $2}’ param_card.dat > m0

cat m0 | while read m0_mass;do

mass[0] = m0_mass;

done

cout<<" your mass is “<<mass[0]<<” "<<$m0_mass<<endl;
[/code]

Thanks in advance

Hi,

You can use FILE *input = gSystem->OpenPipe("wk 'BEGIN{FS="&&"}/&&/{ print $2}' param_card.dat");

Cheers,
