Hello,
I want to make a script which says if a text file is empty or not.
I tried two ways of making it, but I have problems with both of them.
Now I think that the better way is the ls -s solution (considering that an empty text file has a 0 weight, because "cat file.txt" fails when file is... (4 Replies)

I've tried a few options and nothing seems to work. They work just fine if there's text in the file tho. Help? (4 Replies)

setusershell
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.
