replace text
The below command would replace pwdwarntime = 0 to pwdwarntime = 14
cat /etc/security/user | sed "127,200s/pwdwarntime = 0/pwdwarntime = 14/"
But I require to replace pwdwarntime = XX to pwdwarntime = 14
XX mean any value.
Thanks in advance

This is AIX's format. Naturally, they do everything a little bit different. I'd still like to know what madan1278 is *really* trying to do. This sledgehammer approach can't be the best way. It's always dangerous to manually manipulate passwords.
well, I wont claim any expertise in AIX, but I jumped on one:
# uname -a
AIX <edited to save my job> 3 4 000179194C00
# head -1 /etc/passwd
root:!:0:0::/:/bin/ksh
looks "normal" to me. maybe 3.4 is an old version, and IBM has "improved" it! lol

/etc/passwd is pretty much the same, but AIX uses a whole series of files under /etc/security to hold the shadow information, plus a whole lot more.
ah, thanks. ... thus your concern on manual edits, it's all making sense! :)

LINE=`grep -nw "${user}:" /etc/security/passwd| awk -F: '{print $1}'`
PASS=`expr $LINE + 1`
cat /etc/security/passwd | sed "${PASS}s/password = .*/password = */" > /tmp/passwd
mv /tmp/passwd /etc/security/passwd
I follwed the above method. But the comments from dtkerns were useful. As said I will split my points to ozo & dtkerns
Thanks for all ur help.

I have another question for which I have increased the points further up by 75
cat passwd
root:
password = gCwSI.DOGx7Jg
some text here
daemon:
password = jsfdsf.24343444
some text here
madan:
password = 1V5dvL8cAjTSk
some text here
I need to change password = * only for the ID daemon. Is it possible.
Thanks
