Evaluating shell scripts¶
- class sage.misc.sh.Sh¶
Evaluates a shell script and returns the output.
To use this from the notebook type
shat the beginning of the input cell. The working directory is then the (usually temporary) directory where the Sage worksheet process is executing.
- eval(code, globals=None, locals=None)¶
This is difficult to test because the output goes to the screen rather than being captured by the doctest program, so the following really only tests that the command doesn’t bomb, not that it gives the right output:
sage: sh.eval('''echo "Hello there"\nif [ $? -eq 0 ]; then\necho "good"\nfi''') # random output
