Shell oneliner to generate passwords

#password #generate #oneline #shell 
# 10 character random string from specified alphabet
< /dev/urandom tr -dc '[:graph:]' | head -c10; echo
Enter fullscreen mode Exit fullscreen mode

Bash allows redirections at any part of command, so < file command args above is same as command args < file.

Examples:

KrvJz?TgbO
T[7/9Lg9L9
bp[je2Og*l
93:m_Ss$z5
C}Z=-Nj-mn
mG<85C>!i~
%>7/]AWpMd
Enter fullscreen mode Exit fullscreen mode

If you do not want so many special characters, you may use something like: '[:alnum:]_$#%-'
