I have a directory with hundreds of *.doc files,and I want to search a word "t
otal", if the total value is greater than 50, then I want to copy this file to
a new directory,and change the name sequentially to file001.doc,file002.doc .
...sth like that.
So, when I grep "total" ,I got
file1.doc
total: 12
file2.doc
total: 13
file3.doc
total: 56
...
#! /bin/tcsh
foreach wordfile (*.doc)
grep total $wordfile | awk '($2 > 50) {com = sprintf("cp " $wordfile "
../new_dir");print c

Try this:
#! /bin/tcsh
foreach wordfile (*.doc)
grep total $wordfile | awk -v name=$wordfile '($2 > 50) {com = sprintf("cp " name "
../new_dir");print com;}'
end

Hi, that works well, thanks!
But when I tried to use a variable "count" to keep track of how many files con
tain the search string and rename it sequentially in the new_dir, there is a p
roblem.
foreach wordfile (*.doc)
grep total $wordfile | awk -v name=$wordfile '($2 > 50) {count++;com = spr
intf("cp " name " ../new_dir/"count ".doc");print com;}'
end
Is this the same problem?I also tried to initialize this value outside the loo
p, sp, still got problem.
Can you see anything wrong with thi

what you wrote obviously is not what you want according to your description.
I am not a tcsh expert, and wonder who really uses this shell seriously for scripting.
You can use other scripting language such as perl to write one which is more portable.
I can provide another version which is not exactly you want. Good luck.
#! /bin/tcsh
set count=0
foreach wordfile (*.doc)
set count=`expr $count + 1`
grep total $wordfile | awk -v name=$wordfile -v cnt=$count '($2 > 50) { com = sprintf("
