regex - grep for words ending in 'ing' immediately after a comma -


i trying grep files lines word ending in 'ing' after comma, of form:

... gave dog bone, showing great generosity ... ... man, having no home ...

but not:

... great place, having time ...

i find instances 'ing' word the first word after comma. seems should doable in grep, haven't figured out how, or found similar example.

i have tried

grep -e ", .*ing"

which matches multiple words after comma. commands like

grep -i -e ", [a-z]{1,}ing" grep -i -e ", [a-z][a-z]+ing"

don't expect--they don't match phrases first 2 examples. (or pointers better tool) appreciated.

try ,\s*\s+ing

matches first 2 phrases, doesn't match in third phrase.

\s means 'any whitespace', * means 0 or more of that, \s means 'any non-whitespace' (capitalizing letter conventional inverting character set in regexes - works \b \s \w \d), + means 'one or more' , match ing.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
