Off topic:gunzip file.fastq.gz is not working

Question

[kpr]

I am having a basic issue, but I can't figure it out. I have paired-end non-stranded RNA data and I am using it on a UNIX cluster. I type the following code below and nothing happens and I my command prompt disappears.

gunzip file.fasta.gz

The zipped files are in the cluster, I just need my files unzipped.

UPDATE: I'm an idiot, it just took a minute and finally worked.
