I want write a function which changes the working directory by passing the name of a directory variable which has already been established like :

foo () {
   cd $"$1"
}

However when I try , for example, foo links I get -bash: cd: links: No such file or directory

Is it possible to do this ?

You can use variable indirection:

foo () {
    cd "${!1}"
}

dir=/mnt
foo dir
pwd  # /mnt

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
