shell - check whether elements are present in list or not bash -
this question has answer here:
- check if bash array contains value 31 answers
: ${models:=foo bar foobar baz} : ${special_list:=station_tracks user_features} model in $models; echo $model if # model in special list; # how test this? # continue fi done
so, how test whether variable model in special_list
or not?
perl has smartmatch operator ~~
. has been noted, bash , not awk have equivalent, use grep workaround. before continue, if going use bash array, use bash array. syntax going break horribly once beyond simple example, space, gets involved:
models=(foo bar foobar baz) special_list=(station_tracks user_features) model in "${models[@]}" echo "$model" if printf '%s\0' "${special_list[@]}" | grep -fqxz "$model" continue fi done
if prefer can use equivalent long options:
--fixed-strings --quiet --line-regexp --null-data
