Why use the AWK, which, BTW, is a terrific language? It does have some overhead/startup costs. I just pegged myself as a 300Mhz P3 user, didn't I? :)

Use printf with an adequate format string in lieu of print (which has an implied <new line>).

Yes, its because you overwrite the output file with > instead of appending to it with >> redirection operator.

But - why do you chip the "extension" off the file name when it is part of the...

I suppose the problem comes from a misunderstanding about what is done when in the shells evaluation process.

When you write a process substitution in a here-document:

while read line ; do

You're welcome...

From man bash:

So everything inside the here document is standard input to the cat command (not commands that are executed)

Since EOF is unquoted:

Yes but you will need to assign the value to the Index variable outside the here document. You cannot assign a value to a variable inside...

An alternative is to escape the $ sign inside the...

How about:
filenoext=${FILE%.*}
Temp=${filenoext#InputFile}

with awk:
echo "$FILE" | awk '{split($0, F, /InputFile|\./); print F[2]}'
or
echo "$FILE" | awk -F 'InputFile|[.]' '{print $2}'

Hello emily,

You could try following command and let us know if this helps.

echo $FILE | awk '{match($0,/\_.*\_/);print substr($0,RSTART,RLENGTH+1)}'


Thanks,

Hello emily,

Not sure about your complete requirement, could you please try following and let me know if this helps.

echo $3 | awk '{FILENAME=$3"_"int((NR-1)/200)".txt";print >> FILENAME}'

...

The awk variable FILENAME is provided by awk and contains the name of the input file that is currently being processed. Redefining it is not a good idea. Try something like this instead:
awk...

In awk, FILENAME is only defined after the first file has been opened, which is after the BEGIN section has been finished. Within the BEGIN section FILENAME is empty.

Sorry. My mistake. FILENAME isn't defined yet in the BEGIN clause...

Change:
BEGIN {outfile = sprintf("%s_%01d.txt", FILENAME, 0)to:
NR==1 {outfile = sprintf("%s_%01d.txt",...

There seems to be a magic awk command for almost every problem.

csplit might be a far better tool,...

Hello emily/gandolf989,

If we need to split a file according to lines let's say 10'000 lines per file then following may help.

awk '{FILENAME="file"int((NR-1)/10000);print >> FILENAME}'...

Well, gandolf989, that appears to be a poor suggestion given that split will do this all in a single operation. You are wasting IO and CPU resources so it will be quite slow. Also, how would you...

If each entry is a line and you want 10,000 lines try using the
head and tail commands to chop up the file in 10,000 line chunks.
You can probably put it in a for loop with the wc command to see ...

man split.
Did you consider the hints at the lower page border?

Hello emily,

Could you please try following code and let me know if this helps.

You did not adjust the code? The same line seems to be used.

Another thing I noticed is that on this line:

Sample output,

There is a HUGE difference between:
find . -name "*.jpg"and:
find . -name *.jpgbut, if there are no files with a name ending with the string ".jpg" in the directory where you invoke these commands,...

This can be easily mistaken after you have seen something like this

find -name "*.jpg"

which it does actually expands. The find command does not expand the same way the shell does.

* does not expand inside double quotes.

./main "$FILENAME"*.root $LUMIFILE $CONFIGDEFAULTFILE

#!/bin/bash

for f in *_M-130_*.root; do
keep="${f%_?_???.root}"
if [[ "$keep" != "$f" ]]; then
echo mv "$f" "${keep}.root"
fi
done
