The dateutils suite contains a code that can add date/time durations: dadd. However, the format of the durations needs to be not in a form like 1:51:59, but rather 1h51m59s. That can be done with a little pipeline, and then presented to dadd, like so:
producing:
The dateutils suite can be found at dateutils, and in repositories for ArchLinux, Debian, Fedora, FreeBSD, Gentoo, NetBSD, OpenSuSE, OS, Slackware, Ubuntu

If I had a word list with a large amount of words in it, how would I (using a unix command) add, say, 123 to the end of each word?
EDIT: The word list is stored in a large text file. I need a command that applies the ending to each word in the file and saves the result in a new text file. (7 Replies)

endusershell
getusershell(3C) Standard C Library Functions getusershell(3C)NAME
getusershell, setusershell, endusershell - get legal user shells
SYNOPSIS
#include <unistd.h>
char *getusershell(void);
void setusershell(void);
void endusershell(void);
DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If
/etc/shells does not exist, the following locations of the standard system shells are used in its place:
/bin/bash /bin/csh
/bin/jsh /bin/ksh
/bin/pfcsh /bin/pfksh
/bin/pfsh /bin/sh
/bin/tcsh /bin/zsh
/sbin/jsh /sbin/pfsh
/sbin/sh /usr/bin/bash
/usr/bin/csh /usr/bin/jsh
/usr/bin/ksh /usr/bin/pfcsh
/usr/bin/pfksh /usr/bin/pfsh
/usr/bin/sh /usr/bin/tcsh
/usr/bin/zsh /usr/xpg4/bin/sh
The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.
The setusershell() function rewinds the file or the list.
The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.
RETURN VALUES
The getusershell() function returns a null pointer on EOF.
BUGS
All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
