（总结）Linux下多行合并成一行，中间加分隔符

ls lib | sed 's@^@lib/@g' | paste -s -d ":"

ls lib | sed 's@^@lib/@g' | tr "\n" ":" | sed 's@:$@@'

ls lib | sed 's@^@lib/@g' | xargs | sed 's/ /:/g'

ls lib | sed 's@^@lib/@g' | awk "{if(NR%`ls lib | sed 's@^@lib/@g' | wc -l`){ORS=\":\"}else{ORS=\"\n\"};print;}"

ls lib | sed 's@^@lib/@g' | perl -pe 's/\n/:/;' | sed 's@:$@@'
