All of the utilities were present in Ubuntu They were also present in Manjaro Fedora 29 included zip and unzip , but none of the other utilities and that was also the case for CentOS. To create a ZIP file, you need to tell zip the name of the archive file and which files to include in it. The name of the file and the amount of compression that was achieved on that file is shown. If you do not want to see the output from zip as the ZIP file is created, use the -q quiet option.
To include sub-directories in the ZIP file, use the -r recursive option and include the name of the sub-directory on the command line.
To create a ZIP file as before and also include the archive sub-directory, use this command. When the person who receives the ZIP file extracts it, all of the files are placed neatly within a directory on their computer. Note that this command is being issued from the parent directory of the work folder. You can set how much compression is applied to the files as they are added to the ZIP archive.
The range is from 0 to 9, with 0 being no compression at all. The higher the compression, the longer it takes to create the ZIP file. But then, for modestly sized ZIP files, the default compression level 6 is probably good enough anyway. The default compression level is 6. There is no need to provide the -6 option, but it will do no harm if you do. With the selection of files and directories being archived here, the difference between no compression level 0 and the default compression level 6 is K.
The difference between the default compression and the highest level of compression level 9 is only 4K. That might not seem much, but for archives containing hundreds or even thousands of files, the small amount of extra compression per file would add up to a worthwhile space saving. Adding passwords to ZIP files is easy. All of the files that are extracted have the owner set to the user who is extracting them.
Just like zip , unzip has a -q quiet option, so that you do not need to see the file listing as the files are extracted. To have the files extracted in a specific directory, use the -d directory option, and provide the path to the directory you wish the archive to be extracted into. If a ZIP file has been created with a password, unzip will ask you for the password. If you do not provide the correct password, unzip will not extract the files.
If you do not want to extract a particular file or group of files, use the -x exclude option. Suppose you have extracted an archive but you have deleted a few of the extracted files by mistake. A quick fix for that would be to extract the files once again. But if you try to extract the ZIP file in the same directory as before, unzip will prompt you for a decision regarding overwriting the files.
It will expect one of the following responses. To force unzip to overwrite any existing files use the -o overwrite option.
Secure file transfer within SSH is accomplished by two primary commands: scp and sftp, secure versions of the copy and file transfer commands. To begin an SSH session, open a terminal application to gain access to a command line prompt.
The precise method of SSH authentication may simply be a password or public-private key cryptography. How to upload files to a remote server using SSH? If your remote server required the private key to connect server, You can use -i followed by private key file path to connect your server using the SCP command.
This can be helpful for AWS servers. Is there a straightforward way to do this? Improve this question. Floris, do my new comments above help to clarify? To reiterate, I'm just trying to find a way to download a file from command line -- nevermind getting it perfect with options. Could it be as simple as curl -klo etc.? You are using the double dash -- this is for "long" commands. Add a comment. Active Oldest Votes.
On my machine, the following command worked just fine: curl -o. Then it would be curl -ko. Improve this answer. Floris Floris Looks like you have the wrong URL. The following bash script is my end product:! One of my absolute favorite features is that Aria2 can also be used to both download and upload Torrents as a peer and seeder!
It can do this by first downloading the. I primarily use Debian and Arch, so those are the only two I have memorized. Please log in again. The login page will open in a new tab. After logging in you can close it and return to this page. Like what you read? Please share it with others. You should definitely consider switching from Wget and Curl over to Aria2!
