If your using bash you could setup some functions:
Code:
#!/bin/bash
function fill
{
# fill string to width of count from chars
#
# usage:
# fill [-v var] count char
#
# if count is zero a blank string is output
FILL="${2:- }"
for ((c=0; c<=$1; c+=${#FILL}))
do
echo -n "${FILL:0:$1-$c}"
done
}
function pad
{
# Pad to right of string to required width, using chars.
# Chars is repeated, as required, until width is reached.
#
# usage:
# pad [-v var] width string <chars>
#
# if chars not specified spaces are used
BACK=$(fill $1 "$3")
let PAD=$1-${#2}
if [ $PAD -lt 1 ]
then
echo -n ${2:0:$1-1}
else
echo -n "$2${BACK:${#2}}"
fi
}
echo $(pad 10 12121 0) $(pad 10 12121 9)
echo $(pad 10 12121 "-.")
echo $(pad 10 12 "-.")
I need to right-pad with zeros a string by using (s)printf.
I looked up the manual and tried with
printf("%-19s", buffer);
which right-pad the string with spaces. So I tried
printf("%019s", buffer);
which left-pad the string with zeros. So I tried both
printf("%-019s", buffer);... (9 Replies)
I need to read in the string from input file and reform it by cut each segment and check the last segement lenght. If the last segment length is not as expected (see below segment file or table. It is predefined), then pad enough space.

BASHBUG(1) General Commands Manual BASHBUG(1)NAME
bashbug - report a bug in bash
SYNOPSIS
bashbug [--version] [--help] [email-address]
DESCRIPTION
bashbug is a shell script to help the user compose and mail bug reports concerning bash in a standard format. bashbug invokes the editor
specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill in the appropriate
fields and exit the editor. bashbug then mails the completed report to bug-bash@gnu.org, or email-address. If the report cannot be
mailed, it is saved in the file dead.bashbug in the invoking user's home directory.
The bug report format outline consists of several sections. The first section provides information about the machine, operating system,
the bash version, and the compilation environment. The second section should be filled in with a description of the bug. The third sec-
tion should be a description of how to reproduce the bug. The optional fourth section is for a proposed fix. Fixes are encouraged.
ENVIRONMENT
bashbug will utilize the following environment variables if they exist:
EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.
HOME Directory in which the failed bug report is saved if the mail fails.
TMPDIR Directory in which to create temporary files and directories.
