From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

creating an alias of a command with plenty special characters (lemmy.ml)

Hello all, I wan to create an alias of this command: alias dockps = "docker ps --format "table {{.ID}}\t{{.Names}}\t{{.Status}}\t{{.Ports}}""

The syntax for creating an alias is: alias $COMMAND = "docker ps --format "table {{.ID}}\t{{.Names}}\t{{.Status}}\t{{.Ports}}""

However, since there are quote marks, I assume they neet to be escaped with \. But in the case above, I'm getting the errors in fish and bash.

Fish error: $ alias dockps = "docker ps --format \"table {{.ID}} {{.Names}} {{.Status}} {{.Ports}}\""

alias: expected <= 2 arguments; got 3

Bash error: $ alias dockps = "docker ps --format \"table {{.ID}} {{.Names}} {{.Status}} {{.Ports}}\"" bash: alias: dockps: not found bash: alias: =: not found bash: alias: docker ps --format "table {{.ID}} {{.Names}} {{.Status}} {{.Ports}}": not found

What am I doing wrong?

Thanks in advance!

Edit: For fish shell users out there, this can be accomplished by using func: $ function dockerps docker ps --format "table {{.ID}}\t{{.Names}}\t{{.Status}}\t{{.Ports}}" end $ funcsave dockerps

I'm leaving the question up as the question with escape characters is still relevant and can be a learning resouce.

Not at my computer so I can't double check, but I believe you can replace the outer double quotes with single quotes. I'd also remove the spaces before and after the equal sign for the alias. I don't know about fish but I know bash doesn't like when you add spaces there.
