why sub processes not working in tcsh

[a129878]

Why does
vi `grep -il create \`find . -type f\` `
not work under tcsh, returns

Unmatched `.

Its ok in the other shells.

Try that:

vi $( grep -il create `find . -type f` )

 

[a129878]

vi $( grep -il create `find . -type f` )
Illegal variable name.

fairs no better, why should it, they are equivalent.

If it's not just an example, you could use:

vim `grep -ril create .`

IIRC, (t)csh doesn't support more than one level of command substitution. However, you can always convert such expressions to use xargs.
$ vi `grep -il create \`find . -type f\` `
becomes
$ find . -type f | xargs grep -il create | xargs -o vi
