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)

{
print join("\t", $3, $4, $5, $1, $2), "\n";

replace
REPLACE(1) General Commands Manual REPLACE(1)NAME
replace - A utility program that is used by msql2mysql, but that has more general applicability as well. replace changes strings in place
in files or on the standard input. Uses a finite state machine to match longer strings first. Can be used to swap strings.
USAGE
replace [-?svIV] from to from to ... -- [files]
or
replace [-?svIV] from to from to ... < fromfile > tofile
SYNOPSIS
replace [-?|-I] [-s] [-v]
DESCRIPTION
replace
-?|-I info
-s silent
-v verbose
EXTRA INFO
Special characters in from string:
^ Match start of line.
$ Match end of line.
Match space-character, start of line or end of line. For a end the next replace starts locking at the end space-character. A
alone in a string matches only a space-character.
EXAMPLE
this command swaps a and b in the given files:
shell> replace a b b a -- file1 file2 ...
