you are welcome..
sed '1d' deletes the first line of the output:
when i did ps on my system i got :
PID PPID PGID WINPID TTY UID STIME COMMAND
3404 1 3404 3404 con 1006 18:38:19 /usr/bin/bash
2136 3404 2136 3256 con 1006 18:50:10 /usr/bin/tcsh
1920 2136 1920 1160 con 1006 18:50:23 /usr/bin/bash
3312 1920 3312 1488 con 1006 19:48:40 /usr/bin/ps
i am using cygwin not a unix system.
the awk part extracts the 7th column in this case the STIME..
i want to delete the STIME row which is the first row that i deleted using the sed statement..
what is your output of the ps command?

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.
