path, and prints (on standard output) only the name part. For

instance, <literal>stripHash

path, storing the name part in the environment variable
|

<literal>strippedName</literal>. For example:
|
||||
|
||||
<programlisting>
|
||||
stripHash "/nix/store/9s9r019176g7cvn2nvcw41gsp862y6b4-coreutils-8.24"
|
||||
# prints coreutils-8.24
|
||||
echo $strippedName
|
||||
</programlisting>
|
||||
|
||||
If you wish to store the result in another variable, then the
|
||||
following idiom may be useful:
|
||||
|
||||
<programlisting>
|
||||
name="/nix/store/9s9r019176g7cvn2nvcw41gsp862y6b4-coreutils-8.24"
|
||||
someVar=$(stripHash $name; echo $strippedName)
|
||||
</programlisting>
