Folks,
Is there a simple way to replace one digit by two digit using sed.
Example,
mydigit1918_2006_8_8_lag1.csv should be
mydigit1918_2006_08_08_lag01.csv.
I tried this way, but doesn't work.
echo mydigit1989_2006_8_8_lag1.csv|sed 's/]/0]/'
Thank you, (5 Replies)

ExtUtils::Command(3pm) Perl Programmers Reference Guide ExtUtils::Command(3pm)
NAME
ExtUtils::Command - utilities to replace common UNIX commands in Makefiles etc.
SYNOPSIS
perl -MExtUtils::Command -e cat files... > destination
perl -MExtUtils::Command -e mv source... destination
perl -MExtUtils::Command -e cp source... destination
perl -MExtUtils::Command -e touch files...
perl -MExtUtils::Command -e rm_f file...

perl -MExtUtils::Command -e eqtime source destination
perl -MExtUtils::Command -e chmod mode files...
perl -MExtUtils::Command -e test_f file
DESCRIPTION
The module is used to replace common UNIX commands. In all cases the functions work from @ARGV rather than taking arguments. This makes
them easier to deal with in Makefiles.
perl -MExtUtils::Command -e some_command some files to work on
NOT
perl -MExtUtils::Command -e 'some_command qw(some files to work on)'
Filenames with * and ? will be glob expanded.
cat Concatenates all files mentioned on command line to STDOUT.
eqtime src dst
Sets modified time of dst to that of src
rm_rf files....
Removes directories - recursively (even if readonly)
rm_f files....
Removes files (even if readonly)
touch files ...
Makes files exist, with current timestamp
mv source... destination
Moves source to destination. Multiple sources are allowed if destination is an existing directory.
cp source... destination
Copies source to destination. Multiple sources are allowed if destination is an existing directory.
chmod mode files...
Sets UNIX like permissions 'mode' on all the files.
mkpath directory...
Creates directory, including any parent directories.
test_f file
Tests if a file exists
BUGS
Should probably be Auto/Self loaded.
