if bld.env.SAMBA_DIR:
    bld.program(target='winexe-static',
        source='winexe.c svcinstall.c async.c winexesvc32_exe.c winexesvc64_exe.c',
        includes=bld.env.SAMBA_DIR + '/bin/default/include/public',
        cflags='-pthread -include ' + bld.env.SAMBA_DIR + '/bin/default/include/config.h',
        linkflags='-pthread',
        stlibpath=bld.srcnode.abspath() + '/smb_static/build',
        stlib='smb_static bsd z resolv rt',

mean while i am trying head command too...let you know result
Ok, as of now I figured it out with different command that is head -n to remove last 3 lines and append new lines with >>

Code:
[root@ip-xxxxx source]# head -n -3 reptest > tmp.txt && cp tmp.txt reptest
cp: overwrite ‘reptest'? y
[root@ip-xxxxxx source]# echo -e '\t'"stlib='smb_dynamic bsd z resolv rt'", >> reptest
[root@ip-xxxxxx source]# echo -e '\t'"lib='dl ls'", >> reptest
[root@ip-xxxxxx source]# echo -e '\t'")" >> reptest
[root@ip-xxxxx source]# cat reptest
if bld.env.SAMBA_DIR:
    bld.program(target='winexe-static',
        source='winexe.c svcinstall.c async.c winexesvc32_exe.c winexesvc64_exe.c',
        includes=bld.env.SAMBA_DIR + '/bin/default/include/public',
        cflags='-pthread -include ' + bld.env.SAMBA_DIR + '/bin/default/include/config.h',
        linkflags='-pthread',
        stlibpath=bld.srcnode.abspath() + '/smb_static/build',
        stlib='smb_dynamic bsd z resolv rt',
        lib='dl ls',
        )

Hi, I need a sed line that will find all lines that contain "<int key="NSWindowStyleMask">" and then replace the entire line (not just that one string) with "<int key="NSWindowStyleMask">8223</int>". It doesn't necessarily have to use sed as long as it gets the job done :) Thanks (9 Replies)

tcp-env

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME

       tcp-env - set up TCP-related environment variables

SYNOPSIS

       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]

DESCRIPTION

       The  input  for  tcp-env  must be a TCP connection.  tcp-env finds out information about that connection, puts the information into several
       environment variables as described in tcp-environ(5), and runs program with the given arguments.

       Usually tcp-env is run from inetd.  It might instead be run from another server that already sets up the right  environment  variables;  if
       PROTO  is  set  to  TCP  when  tcp-env  is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
       whether the input is a TCP connection.

OPTIONS

       -r     (Default.)  Attempt to obtain TCPREMOTEINFO from the remote host.

       -R     Do not attempt to obtain TCPREMOTEINFO from the remote host.

       -ttimeout
              Give up on the TCPREMOTEINFO connection attempt after timeout seconds.  Default: 30.

SEE ALSO

       tcp-environ(5), inetd(8)

                                                                                                                                        tcp-env(1)
