Disable line wrapping:
1

Linux
Found a good answer from superuser, that works out of the box for gnome-terminal, and probably for other terminals as well:
1
setterm -linewrap off
You can disable line wrapping for less, tail and every other command under the Linux sun with:
1
tput rmam
To restore line wrapping use:

How to delete older Time Machine backups
Delete a file from your Time Machine backup disk - Apple …
| [How to delete older Time Machine backups | iMorewww](https://www.imore.com/how-delete-older-time-machine-backups) |
How can I manually delete old backups to free space for Time Machine?
Be careful with sudo and making sure you pick the correct Mac’s files since there is no undo or confirmation of the following command:
1
sudo tmutil delete /Volumes/drive_name/Backups.backupdb/old_mac_name
The sudo command needs your password (and it won’t echo to the screen, so just type it and pause to be sure you’re dating the correct files before pressing enter). If you want to be safer, you can pick one snapshot to delete first to be sure the command works as intended. This is nice since it could take hours to clean up some larger backup sets and you want to leave the Mac confident it’s deleting the correct information store.
You can use the tmutil tool to delete backups one by one.
1
sudo tmutil delete /Volumes/drive_name/Backups.backupdb/mac_name/YYYY-MM-DD-hhmmss
Since tmutil was introduced with Lion, this will not work on earlier OS versions.
If you want to get the current directory of backups (there can be multiple destinations defined and only one will be “current”)

Fastest way to delete all Timemachine Backups for a machine
If you’ve got:

sudo /System/Library/Extensions/TMSafetyNet.kext/Contents/Helpers/bypass rm -rfv Backups.backupdb

取得最新的 gitlab 备份文件名
对于 gitlab 服务器，当你启用了自动备份功能之后，相应的备份文件会被定时生成。
由于在备份文件夹中有多个 tar 文件，当需要拖回本地时可能往往只想最新的一个，因此需要筛选一下文件名。以下假设你能够自动免密登录到 GITLAB 服务器：

GITLAB_HOST=my-git.com
LOCAL_TARGET=$HOME/Downloads/
FN=$(ssh $GITLAB_HOST 'sudo ls -la --color /var/opt/gitlab/backups/*.tar|tail -1|awk "{print \$NF}"')
# 下载到本地
rsync -avrztopg --progress $GITLAB_HOST:$FN $LOCAL_TARGET
