I have around 50 files that end with .bz2
What command can I run in the terminal to collectively unzip all? I have tried bzip2 -d NT*.bz2 (for filenames that all start with "NT_..." but it is rather slow..
Use the following. bunzip2 *.bz2 If "slow" means the files are processed serially then you could try start a few jobs via a for loop and put them in background. This would still be slow since you are probably running this on a single computer and you are going to saturate the I/O after a certain number of jobs. If you have access to a cluster then you could start them as 50 independent jobs.
