Extract all similar words in a list in shell script-CodePudding

I have a list like below:

list="-list mail-username:123 --list mail-password:xyz --list url:https://www.google.com --list mail_username:123 --list mail_password:xyz --list mail_username:123 --list user_password:xyz"

I want to extract the values of all passwords and store it in a variable.

I tried using sed but couldn't get it.

CodePudding user response：

You could try:

pwds="$(echo "$list" | sed 's/[[:space:]]\{1,\}/\n/g' | sed '/password/!d;s/^[^:]*password:\(.*\)$/\1/g')"

This will not work for passphrases with spaces, though.

CodePudding user response：

This will include the trailing newline in the final password, but since you seem to be playing fast and loose with whitespace, that shouldn't be a problem. (Or, at least, it's not more of a problem than the other issues that will crop up from being cavalier about whitespace!)

echo "$list" | awk '/password/{print $2}' RS=' '  FS=:
