General :: Scripting - Feed An Input File Into An If Statement Line-by-line
Dec 23, 2009I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.
I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.
The error I am getting now is ./script.sh: line 6: [: : integer expression expected
Sample input $FileName

General :: Parse A File And Print Each Line That Ends With Matching Pattern (if The Next Line Is Blank)
Aug 2, 2010I've written a script to parse a file and print each line that ends with matching pattern, if the next line is blank. The pattern lines are the result of md5sum $i|sed 's/path///g' so that only md5 and filename appear. Here's what I'm using.
Quote:
for fline in `sed -n '/.*.ext$/p' file1`
do
if [ "`sed -n -e '/'"$fline"'/ {n; p;}' file1`" == "" ]
then
echo ""$fline" has no info" >>file2

General :: Appending To The Current Line In A File Instead Of Creating A New Line?
Apr 1, 2011I am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test
hello my name is
b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test
b1a:] cat test
b1a:] hello my name is
Bob
b1a:]
So what I would prefer is some command that would create the result:
hello my name is Bob

May 3, 2010My .jar file needs and uses some files in the same directory it's in (everything, including the jar was unzipped into said directory). It runs perfectly when I do java -jar file.jar in the command line, but there's trouble when I double-click the file when running from the file system manager. I've tried a custom command under properties ie java -jar, but the problem is that the .jar file doesn't seem to be able to use any of the files in the same directory. When running, the jar can't find any of the files that it needs.

General :: Restrict Output To Display One File Each?
Jul 27, 2010I use 'grep -Ri "mypattern" .' to search for all files in the current directory recursively that contain "mypattern". But this command returns every single occurence, so that if a given file has several occurences of the pattern, the screen fills up pretty quick. More than likely, there's a way to restrict the output so that it only displays each file once, no matter how many occurences it contains, but I couldn't find how to do it.
