for file in $(ls -ltr *.html | awk '{ print $9 }')
instead of:
Code:
for file in *.html
The second form will not fail due to ARG_MAX limits nor filenames containing whitespace characters; doesn't need to start up a subshell, doesn't need to invoke ls or awk; and will run faster.
All expansions of $file and $filedata also need to be quoted.
It also seems strange that this code replaces everything in every input file with one copy of the text that was supposed to be added after every occurrence of the word <html> in the corresponding input file instead of adding that text to the existing file in the specified spot(s).
Hi Ferocci,
Is the text to be added contained in a file, or is it just a string in your script?
I don't have time to give a complete proposal tonight, but if I was doing this I'd probably use ed -s "$file" in a loop instead of reading the files line by line in the shell (and I certainly wouldn't use echo to copy the results back to the files being processed.
Do you need more help with this?

Hi, What will be the best way to connect (ssh) to hundreds of nodes and grep log files parallely from shell. Using for loop seems to be sequential. Are there any shell built in construct which could be used to achieve this? Is the sub shell any good here? (1 Reply)
