Question

For the following script

install.csh:

#!/bin/csh -f
tar -zxf Python-3.1.1.tgz
cd Python-3.1.1
./configure
make
make install
cd ..
rm -rf Python-3.1.1

Intended use:

./install.csh |& tee install.log

How can I change the script so that I still get a install.log and the output on console without asking the user to do the redirecting?

Answer 1

Some simple solutions:

Solution 1:
tee every line you want to log independently, make use of -a switch of tee to append

#!/bin/csh -f    
tar -zxf Python-3.1.1.tgz |& tee -a install.log
cd Python-3.1.1 |& tee -a install.log
./configure |& tee -a install.log
make |& tee -a install.log
make install |& tee -a install.log
cd .. |& tee -a install.log
rm -rf Python-3.1.1 |& tee -a install.log

Solution 2: Add a second script.
For example, rename current install.csh to install_commands,
then add a new install.csh script:

#!/bin/csh -f 
/bin/csh install_commands |& tee install.log
