I have a bash shell script (AIX) that is the following..
for i in ('cat somefile.txt') do
do something with $i
end
The variables that get passed to $i are in the form of (content of somefile.txt)..
PUB.table1 PUB.CustTable
How can I remove the "PUB." text so that what's passed is only table1...CustTable....etc ?
Thanks.
You can use cut:
cut -d '.' -f2 file | while read i; do echo "$i"; done
table1
CustTable
Or using process substitution:
while read i; do
echo "$i"
done < <(cut -d '.' -f2 file)
You want to test for 0.75-0.8 but wrote code to test for 0.7-0.75 and you forgot to specify what to test in the second part of your condition. Do this: awk '$2 >= 0.75 && $2 <= 0.8' Also note that you want a numeric comparison not a string comparison...

I solved the problem by changing my reduce function so that if there were not the correct amount of fields to output a certain value and then I was able to use the --input-null-non-string with that value and it worked.
From what I understand I would recommend you look in to Applescript as this will allow you to have a GUI Interface as well as executing 'SHELL' commands. First of all I would open 'Script Editor' program that comes preinstalled on Mac's This is an example script which asks for...
The simplest way to do it is to trap the Ctrl+C signal to do nothing but pass the control to the shell script again. I tried the below code and it worked for me. Replace the sleep commands by the real commands you want to execute. #!/bin/bash #Trap the Ctrl+C...

Executable files may be scripts (in which case you can read the text), or binaries (which are ELF formatted machine code). Your shell script is a script; git is an ELF binary. You can use the file command to see more detail. For example, on my nearest Linux system: $...
According to the JSch javadoc, you must call setInputStream() or getOutputStream() before connect(). You can only do one of these, once. For your purposes, getOutputStream() seems more appropriate. Once you have an OutputStream, you can wrap it in a PrintWriter to make sending commands easier. Similarly you can use channel.getInputStream()...
Assuming that your document is well-formed, i.e. <b> opening tags always match with a </b> closing tag, then this may be what you need: sed '[email protected]<[/]\?b>@\n&\[email protected]' path/to/input.txt | awk 'BEGIN {buf=""} /<b>/ {Y=1; buf=""} /<\/b>/ {Y=0; print buf"</b>"} Y {buf = buf$0} ' | tr -s ' ' Output: <b>data1</b>...
Using sqlite3 from bash on OS X seems fairly straightforward (I'm no expert at this, by the way). You will need to find out which table you need. You can do this with an interactive session. I'll show you with the database you suggested: /Users/fredbloggs> sqlite3 ~/Library/Application\ Support/Dock/desktoppicture.db SQLite version...
The 'grep' command uses a regular expression to match text. Use a '^' before the expression, to match from the start of the line. So, you can change the line name=$(echo $hello | cut -d' ' -f9 | grep $1) to name=$(echo $hello | cut -d' ' -f9 | grep...

Just an idea, I didn't see this anywhere but: Unless you're using full paths to invoke those binaries, you could create mocks of those libraries, e.g., in your projects bin/ directory and make that directory be the first in your $PATH. export PATH="$PWD/bin:$PATH" To mock grep, for example, you could...

The most common issue when handling variables containing paths of directories and files is the presence of special characters such as spaces. To handle those correctly, you should always quote the variables, using double quotes. Better code would therefor be: sudo sh "$path/join.sh" sudo sh "$path/join2.sh" It is also advised...

The short answer is - you can't. tee is a separate process with it's own arguments. There is no way to access these arguments from that process. (well, I suppose you could run ps or something). The point of tee is to take STDOUT write some of it to a...

anubhava's solution is excellent if, as they do in your example, the extensions sort into the right order. For the more general case, where sorting cannot be relied upon, we can specify the argument order explicitly: for f in *.ext1 do program "$f" "${f%.ext1}.ext2" done This will work even if...
