Description of problem: Up to RHEL6, if you used the command $ w you would automatically get the "FROM" column in the output. Starting with RHEL7 $ w will omit the "FROM" column. You think, ok, let me use some explicit cmd line option so that the script I'm using on RHEL5/6 will work the same on RHEL5/6 and 7. Alas, this is not possible: on RHEL5/6 $ w -f will take out the "FROM" column on RHEL7 $ w -f will add the "FROM" column. When the w's manual says "-f will TOGGLE" it means it literally :( So, both "w" and "w -f" produce opposite outputs on RHEL7 with regards to previous RHEL versions. On rhel6 the spec file had: W_SHOWFROM=-DW_SHOWFROM On rhel7 it has --disable-w-from ==== Minor issue, on RHEL7, when using "-f", the column labels get misaligned by 1 char (1 space missing between "FROM" label and "LOGIN@" label). Version-Release number of selected component (if applicable): procps-ng-3.3.9-6.el7.x86_64
Hello Giulioo. The w FROM issue has already been reported internally in scope of Bug 1078310. But the minor issue with column alignment you mentioned is something I never noticed before. Good catch. I'll fix that upstream and then backport/rebase in scope of RHEL7. Thanks for the report. Regards, Jaromir.

After testing the patch uploaded above I noticed that fixing one space makes another misalignment if user tries another w's option (-s for example). Because the spaces in headline are mostly hardcoded (!!!) even within upstream version, it is like hit-a-mole game. The entire headline space computation should be reconsidered to be more dynamic, which may exceed the scope of this BZ.
