i have complex grep/awk/etc command line use " $var already, makes impossible use
var="$( command )" to output
i don't want create temp files, make ugly,
is possible pass pipe output variable in bash
like
command | > $var
just use : var=$(complex command ), writing complex command if writing on next line.
ex: if have
foo=1 bar="2 3" awk -v myfoo="$foo" -v mybar="$bar" '..... complex awk script here .....' you put var with:
foo=1 bar="2 3" var="$( awk -v myfoo="$foo" -v mybar="$bar" '..... complex awk script here .....' )" ie, once inside $(...), bash reading things if @ "first level". works $(...) evaluated first before line containing evaluated.
