"rename.pl, a script to rename files in batches, using Perl
expressions to transform their names.
Usage:
rename.pl [options] FILE1 [FILE2 ...]
Where options can be:
-v Verbose.
-vv Very verbose.
--apply Really apply modifications.
-e PERLCODE Execute PERLCODE. (e.g. 's/a/b/g')
--from-charset=CS Source charset. (e.g. \"iso-8859-1\")
--to-charset=CS Destination charset. (e.g. \"utf-8\")
--unicode-normalize=NF Unicode normalization form. (e.g. \"KD\")
--basename Modifies only the last element of the path.

filter fghfilea ok fghreport ok notfghfile notok; mv --filter fghfilea jklfilea; mv
filter fghfilea ok fghreport ok notfghfile notok; auto --all --filter fghfilea "mv fghfilea jklfilea"
# Even better, automatically infers the file name
filter fghfilea ok fghreport ok notfghfile notok; auto --all --filter "mv fghfilea jklfilea"
多步骤的解决方案
要仔细查看命令是否执行良好,您可以键入以下命令:
filter fghfilea ok
filter fghfileb ok
filter fghfileb notok
# for your fgh example. renames all files from "fgh..." to "jkl..."
files = Dir['fgh*']
files.each do |f|
f2 = f.gsub('fgh', 'jkl')
system("mv #{f} #{f2}")
end
# renames all files in directory from "021roman.rb" to "021_roman.rb"
files = Dir['*rb'].select {|f| f =~ /^[0-9]{3}[a-zA-Z]+/}
files.each do |f|
f1 = f.clone
f2 = f.insert(3, '_')
system("mv #{f1} #{f2}")
end
#!/bin/sh
#replace all files ended witn .f77 to .f90 in a directory
for filename in *.f77
do
#echo $filename
#b= echo $filename | cut -d. -f1
#echo $b
mv "${filename}" "${filename%.f77}.f90"
done
