Hello,

Following may help you.

FNR==NR ##### This condition will be true only when file1 will be read #####

You didn't specify the field separator:-
awk -F\| '
NR == FNR {
T = $0
sub(/[^|]*/, X, T)
A[$1] = T
next
}

Hello,

Output will be as follows.

Would this help you ?

We can use following option available in date

%u day of week (1..7); 1 is Monday

%w day of week (0..6); 0 is Sunday

you want to run through a count starting from 0-9 (10), stepping back each iteration as a day in time. Then you want to identify any day that might be a Saturday or Sunday? I think this will work?...

You'll need to fiddle around with some serious escaping, like (and eventually more)$ssh server_name 'for variable in $(ps -fu user | grep -i something/ | grep -i something | grep -v grep | awk...

If you have pgrep then you can probably do
pgrep -u user somethingand no problem to run that as ssh argument.
If you insist in your complex commands, save them in a script command.sh
And run it...

awk 'FNR==NR{A[NR]=$0;next}{print A[FNR]""$0}' top_list.txt_temp_1 top_list.txt_temp

Hello,

with command paste:
paste -d'\0' top_list.txt_temp_1 top_list.txt_temp

Regards.

Try
awk '. . . ; {for (i=12; i<=NF; i++) printf "%s ", $i; printf "\n"}

See note on literal escape character in my original reply

Did you try the tr option to remove control characters?

tr -d [:cntrl:] <filename >output

Try escaping the inner double quotes:


... \"background-color:#FF9933\" ...

otherwise background-color:#FF9933 will be treated as awk code.

This sort of conversation has made many head-level dents in my wall before. "I need array arrays!" "What are you doing?" "I need array arrays!" "But why do you need your data arranged that way? ...

Why - do you think - did I put that eval into the almost identical line 4 above your erroneous line? And, see and read again Corona688's post#8.

Whilst I fully accord with Corona688 about better not suboptimize but take the whole picture into account to find a good solution, here's a small bashism that might do what you're so eager for:while...

I get from that:
1) You have huge files
2) You must output HTML
3) You'd like multidimensional arrays

This actually sounds like exactly the kind of situation awk is meant for. It has things...

We get asked for this more often than you can imagine, but to date nobody's ever given a better reason for it than "it seemed like a good idea at the time". It's always silly -- how would you even...

This is a solution in bash, but you surely can devise a similar ksh thingy:while IFS=\| read -a WORD; do echo -e ${#WORD[@]} "\t" ${WORD[@]}; done < file

To start read -a is bash syntax. The equivalent ksh syntax is read -A

It should not be possible to calculate the reverse. One could use tables, but not calculate the reverse. Even if a md5 happened to be in a table somewhere, there is not guarantee that it would be the...

A log file with one line per background process is nice, as you can grep or count the tightly structured records.
But file per process in the background in a dedicated directory is the most...

Some systems even have pgrep, but if the running background task subshell leaves a marker file, that is a cheaper test. Besides, pids get reused.
