The only worry I'd have about modifying the same file repeatedly is that the table of contents must be changed, every time. It's not simply adding to the end. Mess up the table of contents and the...

Depends what you mean by "zip file".

If you mean zip file as in an honest-to-goodness, pkware-compatible, old-fashioned .zip file as created by the zip and unzip commands, then yes. Files in .zip...

The while loop will abort at the first empty field because $i != "" evaluates to false. With the sample data provided and with the field separator you're using (any non-digit), the comparision is...

Someone, tell me what's wrong with this code, please?
awk -F'[^0-9]' '{s="";i=0;while(++i<=NF&&$i!="")s=s$i"\t"}$0=s' file

tr -cs '[:digit:]' '[\t*]'

~/unix.com$ awk -F'[^0-9]' '{s="";for(i=1;i<=NF;i++){if($i!="")s=s$i"\t"}print s}' file

perl -ne 'while(/(\d+)/g){print "$1\t"}' inputfile

You probably don't want to use cut, it's fast but inflexible (to the best of my knowledge you cant have a variable delimiter). try the following approach:

perl -e 'print...

Hi,
Try this,

awk '/M0271857/{l=length($0);if(min==""){min=l;r=$0;}else{if(l<min){min=l;r=$0;}}}END{print r;}' file

Cheers,
Ranga:-)

awk '/M0271857/ && ((!L) || (length(L)>length($0))) { L=$0 } END { print L }' datafile

Meaning:

/M0271857/ # for all lines where your string matches
&& ((!L) || (length(L)>length($0))) #...

If you are doing this within a loop, you may want to consider using the built-in feature of bash/ksh parameter expansion. This will save you 1 exec for every loop

v="abc/def/ghi/jkl/mn.txt"
echo...

Try using basename <full_path_to_file>

$ basename /sndc002/app/appsndc/sndcappl/admin/sndc01.txt
sndc01.txt

$ echo "abc/def/gh/joe.txt" | awk -F"/" '{print $NF}'
joe.txt

Like shown, it's a textfile named radar.awk

It's not perl, it's awk.

You run it as shown, awk -f radar.awk filename

The data is printed to the screen, as shown.

awk -f radar.awk filename...

That's a pretty ugly input file, unless it was originally tab-separated and ruined by copy-pasting it into a web postbox, but:

$ cat radar.awk

BEGIN {
OFS=","

Hi sunnydanniel,

Put here the spreadsheet you want as output. It will be helpful for anyone who would like to help you.

The -F is necessary. () are special characters to the shell and to grep. You must prevent the shell from expanding them with "", and grep from interpreting them with -F.

My version of egrep...

Quote it too.

egrep -F "R1_980302_105147(2)" namelist.txt

You can also try this method eliminating the use of the cat command and making sure to include quotes around the $line variable.


while read line
do
echo "$line"
blah blah "$line"...

That won't work either. That will make it all one giant filename instead of a list of files!

The problem isn't how you're using the for-loop, the problem is you're using backticks to shoehorn a...

try this way ( doublequotes )

for F in "$FILES"

For completeness, here is the sed command:
sed 's/..//' file

You don't need sed for such a simple task: cut -c3- file
