./script.sh 2> logfile.log

Thank you!

How do you mean combine? You want both of their output to go to the log file? — Tom Fenech

Is it two different scripts? If so then use: ./s1.sh > log; ./s2.sh 2>> log see the append >> — Andreas Louv

In bash, to redirect both standard output and standard error to the same file, you can write

./script.sh &> logfile.log

If you want to be compatible with other shells,

./script.sh > logfile.log 2>&1

The first only works in bash 4+

When you are logging, you might need to append log file instead of overwriting it, so simple change to ./script.sh >> logfile.log 2>&1.

thank you! second option works perfect )
