This is a bit unintuitive, but in fact it comes from the structure of the filesystem itself. Filesystems in UNIX (any UNIX filesystem i know so far) rely on "inodes", which hold the files metadata...

The standards require that "standard utilities" have to be available as stand-alone utilities so you do things like:
find dir -exec utility arg... \;
The only utilities defined by the standards...

Hi,

on Debian Linux + Bash:
type unset
unset is a shell builtin

You are grep'ing for local/init.d/abc, but ls output is only abc, so it cant find it.
grep only for abc, and you should see output.
Also, your first code has no closing done.

Furthermore, you...

man bash:

Don't pipe the echo, connect the two by either ANDing them:echo -n "kernel.sem = " && cat /proc/sys/kernel/sem
or a group command (compound command):{ echo -n "kernel.sem = "; cat...

So why are you using awk for either of these?

read x semmns < //proc/sys/kernel/sem
read shmmax < /proc/sys/kernel/shmmax
[ "$semmns" -lt 33000 ] && printf 'semmns: %d\n' "$semmns"
[ "$shmmax"...

Try:
LC_ALL=C tree

It picks it from the first path it finds it in (unless you specify a path when running it).

From the (shell) prompt, type:

which mv


For me, it's:

$ which mv
/bin/mv

You need to use cp and rm if:

there are multiple hard links to the file you are overwriting,
you need to preserve file modes that might be different from what would be set using your current...

First, be sure that you have a back-up copy of sysctl.conf before you try this. Then try something like:
nawk '
/kernel.sem/ {
if(($3 + 0) < 300)
sub($3, "300")
else exit(1)
}
1'...

Hello Stew,

Could you please try the same and let me know if this helps, kindly try the same first with same details a test file
and if All is Well then you can try with actual file too.

cat...

sub($1,"300",$0) - Sub() replaces first field by 300 in $0 (entire line read from file test)

awk '{ if ($1 < "300") { sub($1,"300",$0); print > "/tmp/test" } }' /tmp/test

Store all hostnames in a file ("servers" for example)...

cat servers

Hello,

Could you please use the following code.

Output will be as follows.

Try:
awk '/ n /{print "insert into lastlogon values(" q $1 q ", " q $3 q ", "q $4 q", "q $5 q", " q $6 q ")"}' q=\' userreport.txt
or
awk '/ n /{print "insert into lastlogon values(" q$1q, q$3q,...

There are a number of reasons why this will not work:

First, "INSERT INTO <tablename>" is not a valid statement, because there is nothing specified to insert into the table at all. If you haven't...

Looks like you missed read in your program 2, message #16

With the input file shown above, the simple way to get the output you requested is:
grep -e '^On since' -e '^Last login' input_file
