The only dependable things cron gives you are the SHELL, LOGNAME, and HOME environment variables as determined from that user's /etc/passwd entry. The rest just gets inherited from what cron had,...

netstat -a | grep -w 9071 |grep ESTABLISHED | awk '{print $5}' | cut -d'.' -f1
This can be reduced from 5 commands to 2

Only if the closing EOF is indented with a TAB (or nothing at all - it won't work if those are spaces before it).

You could use use awk:

awk 'NR == FNR {
iton[$1] = $2
next
}
($1 in iton && $1 = iton[$1]) || 1
' file2 file1 > _tmp_file_ &&
mv -- _tmp_file_ file1

If the original order is...

Doubtless you can simplify the code further, i.e. by using awk to read both files and substitute the correct values. You would then write this to a temporary file and copy that over the original.

Please check the output of my command and not the input file.

Hey,

Welcome to The UNIX and Linux Forums,

Please use code tags for data samples and codes. code tag button look like https://www.unix.com/images/editor/code.png

You should use printf to...

Hi sathyaonnuix, A[NR%y] has the function of a rolling buffer, it contains a number of lines that is equal to y, which is the number of lines that should not be printed at the end of the input file.....

Try sth like this...

Something like this?

Hi

Guru.

You can just sum it up as you go through each line:

$ cat myScript
awk '{
TR=0
for( I = 1; I <= NF; I++ ) {
TR += $I
TC[I] += $I
printf( "%6d", $I )
}
print " = " TR...

I am not sure if this is correct:
sed -n '/^\.\.\.\./!H; /^\.\.\.\./{x; /stopped/d; /date.*13\/12\/2012/d; p;}' example

The offset in TZ for GNU date (or libc?) seemed can't be bigger than 24. You need to convert the day part into -d argument as you said. Either override your date command with a function:

$0 means 'the entire unmodified line', pure and simple. You can change what 'line' means to awk, but by default, it uses newlines like everything else.

You can think of it as a hash table if you...

Your wget example retrieves a https-URL. You have set a http-proxy in wgetrc, but not a https-proxy. Add


https_proxy=http://str-www-proxy2:8080
to your wgetrc file and retry.

Append http://en.wikipedia.org and then use wget.

You're making this much too hard on yourself. When you set a variable in the shell, parameter expansion occurs in double quoted strings and that is all you need here.
Adding the eval also causes...
