In Dired mode, to modify marked files according to a specified regular expression, as known, push "Q" after you marked them.
However, I find I can't use "\\1" to quote strings between "\\(" and "\\)" (By the way, strangely, it seems that I must use "\(" and "\)" instead in such "Q" interactive query mode).
For example, some files has below style:
---------------------------------------
...
aaa
bbb
ccc
...
---------------------------------------
And I want to add a line "XXX" between "bbb" and "bbb".
I use "^\(a+\)$" for regexp and "\1\nXXX$" for substitue string, but it fails ...
On the other hand, I succedd using my perl script:
-----------------------------------------
#!/usr/bin/perl
($#ARGV <= 0) || print "Your must input filename to process!\n";
open OBJFILE, "$ARGV[0]" or die "$!";
open TMPFILE, ">_tmpfile";
while (<OBJFILE>) {
s/^(bbb$)/$1\nXXX/g;
select TMPFILE;
print;
}
`mv -f _tmpfile $ARGV[0] && rm -f _tmpfile`;
-----------------------------------------
