* doc/coreutils.texi (dircolors invocation, Examples of expr):
(shred invocation, seq invocation): Use $(...), not `...`.
* src/mv.c (do_move): Likewise, in a comment.
Typical usage:
@example
-eval "`dircolors [@var{option}]@dots{} [@var{file}]`"
+eval "$(dircolors [@var{option}]@dots{} [@var{file}])"
@end example
If @var{file} is specified, @command{dircolors} reads it to determine which
For example:
@example
-i=`mktemp`
+i=$(mktemp)
exec 3<>"$i"
rm -- "$i"
echo "Hello, world" >&3
To add 1 to the shell variable @code{foo}, in Bourne-compatible shells:
@example
-foo=`expr $foo + 1`
+foo=$(expr $foo + 1)
@end example
To print the non-directory part of the file name stored in
to perform the conversion:
@example
-$ printf '%x\n' `seq 1048575 1024 1050623`
+$ printf '%x\n' $(seq 1048575 1024 1050623)

parent. It doesn't make sense to move a directory into itself, and
besides in some situations doing so would give highly nonintuitive
results. Run this 'mkdir b; touch a c; mv * b' in an empty
- directory. Here's the result of running echo `find b -print`:
+ directory. Here's the result of running echo $(find b -print):
b b/a b/b b/b/a b/c. Notice that only file 'a' was copied
into b/b. Handle this by giving a diagnostic, removing the
copied-into-self directory, DEST ('b/b' in the example),
