If the last column is equal "R" then... Is it possible? In unix
With awk you can try:
awk '$NF=="R"' <<< "$var"Test:
$ var="this is a var with last as R"$ awk '$NF=="R"' <<< "$var"this is a var with last as R$ var1="This should not be printed"$ awk '$NF=="R"' <<< "$var1"$
The condition can be:
if [[ $value == *' 'R ]]then echo $valuefiNo need for an external language, like awk.
Using the =~ binary operator:
$ var="Some arbitrary string ending in R"$ unset value$ [[ "$var" =~ $'R$' ]] && value=${var}$ echo $valueSome arbitrary string ending in R$ var="Some arbitrary string ending in Q"$ unset value$ [[ "$var" =~ $'R$' ]] && value=${var}$ echo $value
