so have been battling time , first post here. wanted know, if passed in container forward container, defined in boost, how can write code in way further checks see if code either backinsertionsequence or frontinsertionsequence , executes depending on type is? template <class sequentialcontainer> void myclass<sequentialcontainer>::saysomething() { boost_concept_assert((boost::forwardcontainer<sequentialcontainer>)); if (boost::backinsertionsequence<sequentialcontainer> == true) { //do } else { //say else } } if did if check have there, both branches have compiled regardless of fact 1 branch ever executed particular type. severely limits usefulness of simple if - need construct such 1 of branches compiles. there 2 common ways of doing this. tag dispatch: template <class sequentialcontainer> void myclass<sequentialcontainer>::saysomething() { saysomething<sequentialcontainer>...

i have file such: 1 role 2 role b what i'd search string "role a" , return value 1 in variable. so following: if grep "$i" role_info.txt <assign variable number associated string> else <no search string found - else> fi if columns delimited tabs can do: role='role a' number=$(awk -v role="$role" -f '\t' '$2==role {print $1}' role_info.txt) if it's spaces, try instead: role='role a' number=$(grep "$role" role_info.txt | cut -d' ' -f1) either way, can check if match found with: if [[ -n $number ]]; # number found else # not found fi another option is: while read number role; if [[ $role == 'role a' ]]; # match found fi done < role_info.txt this bit more robust: role has second item on line; can't in first position.
