scottn,

thank you for your Patience.

The first solution:

The second one:

awk 'NR == FNR {...

"all patterns" means: returns every line that contains any string pattern from the pattern file. And the...

thank u for your quick replay...but it does not work ..

I need something faster than the following solution:

for i in `cat pattern_file`

grep $i input_file1 >> output_file1
grep $i ...

I have the following situation:

a text file with 50000 string patterns:

abc2344536
gvk6575556

lorcan,

lorcan,

>Do you want an exact pattern that matches the files like "abc_20070710_123.txt" ?

Thank you

kamitsin, how to solve the problem in "regular expression" not with grep -v ???

how to list all text files except the files from 20070712:

abc_20070710_123.txt
abc_20070711_123.txt
abc_20070712_123.txt

ls *.txt | egrep"[a-z]+_^20070710_[0-9]+\.txt"

Any idea...

Jim,

please try the command to remove a lot of white spaces:

content of file:
<space><space><tab><space><tab><space><tab>hello

Andy

Sorry, but I 've said:

sed 's/^[ \t]*//' file # works only on Linux but NOT on HP-UX

the sed command:

sed 's/^[ \t]*//' file

does not work on HP-UX :-( but it works fine on Linux,

content of file:
<tab><tab>hello

output should be:
hello

Any ideas??

Thank you...

please help:

I want to add 1 space between string and numbers:
input file:
abcd12345
output file:
abcd 1234

The following sed command does not work:

sed 's/\([a-z]+\)\([0-9]+\)/\1 \2/'...
