问题 I am using ssh to work on a remote server, however when I try to download a file using scp in this format: scp name@website.com:somefile.zip ~/Desktop It asks me for my password, and shows this: somefile.zip 100% 6491 6.3KB/s 00:00 however, this file never appears on my desktop. Any help 回答1: I think that you are logging into the remote machine using ssh and then running the command on the remote machine. You should actually be running the command without logging into your remote server first

问题 I am trying to check a string for any Uppercase letter. my code shows NO UPPER for any input, may it be "sss", "Sss", "SSS" if [[ "$pass" =~ [^a-zA-Z0-9] ]] then echo "Upper found" else echo "no upper" fi 回答1: [^a-zA-Z0-9] means anything except for a-z , i.e. lowercase letters, A-Z , i.e. uppercase letters, and 0-9 , i.e. digits. sss , Sss , SSS all contain just letters, so they can't match. [[ $password =~ [A-Z] ]] is true if the password contains any uppercase letter. You should set LC_ALL

问题 I have a simple one-liner that works perfectly in the terminal: history | sort -k2 | uniq -c --skip-fields=1 | sort -r -g | head What it does: Gives out the 10 most frequently used commands by the user recently. (Don't ask me why I would want to achieve such a thing) I fire up an editor and type the same with a #!/bin/bash in the beginning: #!/bin/bash history | sort -k2 | uniq -c --skip-fields=1 | sort -r -g | head And say I save it as script.sh . Then when I go to the same terminal, type
