So, I ran this snippet:
editfiles:
{ /tmp/tabtest
DeleteLinesMatching "REGEXGOESHERE"
}
With the obvious substitution for the following:
^\t\t$ (tab tab, the "\t" entries indicate "real"
tabs, not a literal '\' then 't'
^${tab}${tab}$ (tab tab)
^8${tab}${tab}$ (digit tab tab)
^8${tab}${tab}8$ (digit tab tab digit)
^ $ (space space)
^${spc}${spc}$ (space space)
My sample file had lines with (spelled out in english...):
only two tabs in it
a space, then a tab
a tab, then a space
a space, then a space
two tabs, then a digit
a digit, then two tabs
a digit, then two tabs, then a digit
Each one removed the lines I expected to be removed: that is the
"space space" lines would remove only lines with 2 spaces.
Although not mentioned, I also tried these
^[:space:]+$
^[:blank:]+$
^[:space:]*$
^[:blank:]*$
but none of them worked at all. (I realize this is a tangent of sorts).
All testing was done using cfengine 2.2.0
