I wish to learn how to use the alias command in .cshrc
I need to change some Unix commands, like :
change "rm -f " into "rm -i "
or to write small scripts using alias.
alias rm 'rm -i'
alias cp 'cp -i'
alias mv 'mv -i'
I add this line to .cshrc file
alias rm -f 'rm -i'
Then exit the user and reenter again to the user .
Then i run the command
rm -f filename in the command line.
And I get error:
-f: Command not found
I am not sure that this is the way to solve it????
Well, just try alias rm 'rm -i' like mib suggested ... most of the time, the -i option overrides the -f option. So if you use that alias and then someone types "rm -f", the -f option will be ignored.
I did what you told me to do.
I put the rm 'rm -i' line into the .cshrc exit the user renter again and it didn't help.
i ru the command rm -f filenam and it has been removed without asking if i am sure.
??
so its not working.
Read this for a quick tutorial on creating aliases.
Read this to see how to make the aliases stick between logins.
You need to edit the .cshrc file in your home directory and enter each alias command on a separate line. Then it'll be there when you login next time.
I add this line to .cshrc file in a separate line
alias rm 'rm -i'
Save it.
Then exit the user and reenter again to the user .
Then i run the command
rm -f filename in the command line.
And the file was removed without asking ??
I already know all the aliases rules !
If you test your suggested command you will see that its not working !
10x.
man rm
-f Attempt to remove the files without prompting for confirmation, regardless of the file's permissions. If the file does not exist, do not display a diagnostic message or modify the exit status to reflect an error. The -f option overrides any previous -i options.
