It means what it says, it had trouble reading one (or more) of the input files, as one might exepct of a dying hard drive. But it didn't actually quit, it waited until it was done to quit with error.

tar shouldn't die halfway, just continue and print warnings. GNU tar, anyway. Good luck.

If you keep poking at your drive while it is "making funny noises" you are going to lose it completely. Make a raw dd copy if you have to, but get the contents off!

Either that, or stop poking at...

First I would try to modify your "crontab -l" command so that information is easy to extract from this bit messy file, adding hostname for later convenience in parsing. Try running this instead of...

I'd say go with learning Perl if you want to keep being competitive in the job market. Perl scripting is highly desirable skill for SysAdmins.

I would recommend that you begin learning perl. While at it, probably become better at sed and awk. There is no best, merely different tools to be used at different times.

Can you bang a nail in...

The order I learned things:

perl, shell, awk.

The order I wish I'd learned things:

shell, awk, perl.

They all have their uses... If you find yourself writing system() over and over, it...

Hi, try:
awk 'NR==1{h=$0} $1~/\.$/{print h RS $0 RS}'

or perhaps this is more like what you are after:
awk 'NR==1{h=$0} sub(/\.$/,x,$1){print h RS $0 RS}' OFS=,

You left out
OFS=, ORS=
at the end of your awk..

/usr/xpg4/bin/awk 'p!=$1{if(p)print RS; print p=$1,$2}{for(i=5;i<=NF;i++)$4=$4 FS $i; print OFS $3 "=\"" $4 "\""} END{print RS}' OFS=, ORS=...

By the by, that's a useless use of cat (http://partmaps.org/era/unix/award.html). You almost never need cat to read a file, programs are perfectly capable of reading files themselves, and even if...

printf is a function found in many different programming language for convenient formatting of numbers and strings. Its first argument describes how to format all the arguments afterwards when...

Hi, try END {printf "%d\n",sum/6} or END {printf "%.2f\n",sum/6}

pidfile=/var/tmp/stats.pid

# exit if another is running
[ -e "$pidfile" ] && exit

# create pid file
echo $$ >"$pidfile"

# delete pid file on exit (may have to do this definitely depending...

Might need something like this for the *Name fields:

awk 'p!=$1{print (p?RS:"")(p=$1),$2;} {for(i=4;i<=NF;i++)printf(i>4?" ":OFS $3 "=\"") $i; print "\"" } END{if(p)print RS}' OFS=, ORS= infile

Hi, see if this works:
awk 'p!=$1{if(p)print RS; print p=$1,$2}{print OFS $3 "=\"" $4 "\""} END{print RS}' OFS=, ORS= infile
