Description
This statement runs the hasher in a subshell:
$command | tee >( decompress "$decompressor" "$TO" ) \
>( hasher $HASH_TYPE ) >/dev/null
However, it may happen that the hasher has not yet finished writing the hash value to a file when this instruction is executed:
HASH_RESULT=$( cat $HASH_FILE)
A workaround would be to poll the existance of the file before doing the cat.
