ok it is a lot. if you put in separate file and make executable, you run ./script users > upload-file. or you can put all of it in single quotes and use it inside of existing shell script:
so it gets the user file as parameter. it first runs getent itself, once, instead of many times and grepping it etc. in the end it will only print groups which it added users to.
awk is quick at text manipulations. probably the rest of the script would incorporate well into it.
How can I retrieve the group id of an entry in the /etc/group file given the group name?
I tried using cut and grep but cant get around the problem..
I think this problem can be solved using these commands but I dont know how (I am a newbie at this) (11 Replies)

Hi,
I need to do some section/group sorting. At the moment, I get around it by grep group by group and then re-directing to the same 'final' output file.
Below is what's been sorted so far based on the second field
$ awk -F"," '{ { print $5 " == " $6 } }' /tmp/x.csv | grep -v "^env" | grep... (2 Replies)

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
