Large file split and join in linux Rumi, July 19, 2021 Let’s assume we have a large file of 102 GB and named as “vzdump-lxc-103-2021_07_19-12_05_06.tar.lzo”. We’d like to split this large file into 10GB of partial file. Let’s apply the split command as below- split -b 102400M vzdump-lxc-103-2021_07_19-12_05_06.tar.lzo repo. Wait for a while, the execution continues, and once over, you’ll find 11 split files altogether- root@ktlhost4:/mnt/pve/nfs-1/dump# ls -lah total 203G drwxr-xr-x 2 root root 4.0K Jul 19 15:04 . drwxr-xr-x 7 root root 4.0K Jul 14 19:39 .. -rw-r--r-- 1 root root 10G Jul 19 14:53 repo.aa -rw-r--r-- 1 root root 10G Jul 19 14:54 repo.ab -rw-r--r-- 1 root root 10G Jul 19 14:55 repo.ac -rw-r--r-- 1 root root 10G Jul 19 14:56 repo.ad -rw-r--r-- 1 root root 10G Jul 19 14:58 repo.ae -rw-r--r-- 1 root root 10G Jul 19 14:59 repo.af -rw-r--r-- 1 root root 10G Jul 19 15:00 repo.ag -rw-r--r-- 1 root root 10G Jul 19 15:01 repo.ah -rw-r--r-- 1 root root 10G Jul 19 15:03 repo.ai -rw-r--r-- 1 root root 10G Jul 19 15:04 repo.aj -rw-r--r-- 1 root root 1.3G Jul 19 15:04 repo.ak -rw-r--r-- 1 root root 102G Jul 19 13:23 vzdump-lxc-103-2021_07_19-12_05_06.tar.lzo Now it’s time join the split files, so here it goes- cat repo.?? > vzdump-lxc-103-2021_07_19-12_05_06.tar.lzo Your slit files are not joined in a single file again.
