Files do not work that way. You can't write to the same file you're reading from. A few commands can pretend, but they're really using temp or whole-memory buffers files like everything else does:
I have two files file1 and file2 as shown below:
file1:
name
nameabc
bcd
nameabcdefg
file2:
age
age1111
age2345
age6743
I have pasted one file on the other with the delimiter "|" and the resulttant file is:
name|age
nameabc|age1111
bcd|age2345
nameabcdefg|age6743 (1 Reply)

ns_mktemp
ns_tmp(3aolserver) AOLserver Built-In Commands ns_tmp(3aolserver)__________________________________________________________________________________________________________________________________________________NAME
ns_mktemp, ns_tmpnam - commands
SYNOPSIS
ns_mktemp template
ns_tmpnam
_________________________________________________________________DESCRIPTION
ns_mktemp returns a unique filename based on the template you specify. ns_tmpnam returns a filename that can safely be used for a tempo-
rary file.
The template for ns_mktemp should contain a string with six trailing Xs, which will be replaced with an alpha-numeric string of six charac-
ters chosen to make the filename unique. If template does not end with six trailing Xs the empty string will be returned.
ns_tmpnam calls the tmpnam() C library function, and the results will depend on your operating system. On Irix, for example, tmpnam()
always generate a file name using the path-prefix defined as P_tmpdir in the header file which is "/var/tmp/".
EXAMPLES
nscp> ns_tmpnam ;# On Linux
/tmp/filevuLwaE
nscp> ns_mktemp /tmp/foobar.XXXXXX
/tmp/foobar.p6SlaC
