Ah, the libsmartcols provides a filter. See, for example, misc-utils/lsblk.c and the "-Q" command line option, and also "man scols-filter". scols_new_filter() scols_line_apply_filter() scols_line_is_filled() ... etc. https://www.kernel.org/pub/linux/utils/util-linux/v2.41/libsmartcols-docs/libsmartcols-Filters-and-counters.html The filter allows the creation of complex queries, so if we integrate it into lsirq and irqtop, it will be possible to use things like: irqtop -Q 'NAME ~= "PCI\-.*" && TOTAL > 100' Karel -- Karel Zak <kzak@xxxxxxxxxx> http://karelzak.blogspot.com
