Hi,
I am currently writing BASH shell scripts. I am using BASH on a Powerbook G4 running Leopard. Could somebody please explain the difference between
#!/bin/bash and #!/bin/sh?
I have been using the latter (#!/bin/sh), and things have been working fine. But is that the correct one to use... (9 Replies)
Do we need to include the exclamatory mark in the shebang line??:confused:

Can any one tell me how to replace a shebang line of a file using sed?

Hi,
I always thought that #!/usr/bin/ksh means that the script would be executed in korn shell i.e. when we'll execute the script with this line as the very first line then the shell spawns a korn shell (in this case as we are using #!/usr/bin/ksh ) and the script gets executed.
But I am... (7 Replies)
Hi,
I have a trivial question to ask, I am seeing in some shell scripts the '-' (hyphen) character following the first line of shell script (i.e) the shebang notation as follows:
#!/bin/sh -
#! /bin/bash -
what does the hyphen signify? What will happen if it is not given explicitly? (2 Replies)
Hi ,
I know about the shebang line in shell scripting. Just want to know whether is there any difference in execution of the program by keeping and not keeping the shebang line. Because without shebang line also the script is working. correct me if am wrong. Any help on this will be helpful (5 Replies)

getusershell
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/ksh93 /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/ksh93 /usr/bin/pfcsh
/usr/bin/pfksh /usr/bin/pfsh
/usr/bin/sh /usr/bin/tcsh
/usr/bin/zsh /usr/sfw/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.
NOTES
Restricted shells should not be listed in /etc/shells.
