I need to get the value of 'uid' from a line in file f1. For example, in the line below, I need to get the value '150', from the 'anonuid=150' key, and I need to verify that this is a valid uid by checking it against /etc/passwd (i.e) I want to compare this uid, 150 (or more if there are any more entries in
f1) to the 3rd field in /etc/passwd file. If there is a match with the entries in /etc/passwd file then this uid should be displayed.
gives me the expected result 150
However, the below command is not working as expected
I have one entry having uid=150 in /etc/passwd.
Please suggest me what correction I should make to the above command to make it work

Hi,
Can anyone help me in understanding how the below code works?
echo "texxt" | sed 's///' gives output exxt, ideally it should give xxt. as this should remove the chars which is not x.
echo 'x_a_b_a_c_a_d' | sed 's/.*\(a\)/\1/'

getpw(3C)getpw(3C)NAME
getpw() - get name from UID
SYNOPSIS DESCRIPTION
searches the password file for a user ID number that equals uid, copies the line of the password file in which uid was found into the array
pointed to by buf, and returns 0. returns non-zero if uid cannot be found. The line is null-terminated.
This routine is included only for compatibility with prior systems, and should not be used; see getpwent(3C) for routines to use instead.

passwd(4).
