I'm using sed to remove certain line in a text file based on a match with 2 variables from input. Here is how it looks like in file
Philip S:Odds:45:343
Mike Junior:Odds:3:56
I prompt for 2 inputs in variable form which is compared to the first 2 fields of the above text (: seperated). So say i enter Philip S and Odds then it should delete the entire first line.
I am writing a bash script to run everyday and output results to a file. When the same results are produced i want to overwrite the line from the previous day. (Or remove and add). So if the script finds a variable in a line. i want it to output the results to that line . sed -i did not work for me; sed: couldn't open temporary file ./sedTvOCEg: Permission denied

I have been searching most of today and am stuck on getting a variable into an awk portion of my bash script. I have this working:

Can awk take a shell variable? Or do I have to do something completely different?
Using things like awk/sed, but have managed to cobble together what I needed so far without a problem. The only thing I'm struggling with is to assign the content of a particular line as a variable, and then to use it again throughout the file.
For example, if what I want is the first line of the file to become the variable "from1", and then to replace the word "Subject" in the file with the string "Message from [from1]". What I thought would work
I tried a few diff combinations but nothing seems to work. All I get is the terminal hanging indefinitely.

I am somewhat confident that there is a neater way.

I have some messy code that I wrote a while back and I am trying to organize it. The program opens xpaint and uses xwit and xte to draw packman and so on. I want to split it all up I am going to add more to it. Basically like i would want drawing packman in one function i guess you could call it and then coloring him or the background in another
<code>
#!/bin/bash
pkill xpaint
res=`xwininfo -root | grep geom | sed -e 's/^.*try ([0-9][0-9]*x[0-9][0-9]*)+.*$/1/'`

Yoriginal=`echo $res | cut -d 'x' -f 2`
X=`echo "($Xoriginal/2)-400" | bc `
Y=`echo "$Yoriginal/2" | bc `
#t=$(($Y/2))
bob=`echo "$Y/2" |bc `
echo $X
echo $Y
/usr/bin/xpaint -size "$Xoriginal"x"$Yoriginal" -popped &
sleep 4
paintersMom=`xwit -all -print | grep XP | cut -d ":" -f 1`
canvasWin=`xwit -all -print | grep Untitled | cut -d ":" -f 1`
#toolres=`xwininfo -id $paintersmom | grep geom | sed -e 's/^.*try ([0-9][0-9]*x[0-9][0-9]*)+.*$/1/'`

xte 'mouseup 1'
#xwit -id $paintersMom -focus -raise
#sleep 1
#xwit -id $paintersMom -warp 30 390 #// fill in command on tool bar

Here for example $paintersmom is would be in the drawing of pacman but I would also want to use it when I colored him in.. but I would want both processes in a different shell script.
What I am trying to accomplish is a way to read only the lines that have been added to the file mylog0 since the last time the script looped (5 seconds). I am open to new suggestions too, I have been stuck on this little script for a few hours already.
Code: #!/bin/bash
i=0
firstline=0
[code]...
Code:
grep -r $SEARCHDIR --include="day_$YYYY-$MM-*" -h -o -e PATTERN
The above command does exactly what I want: limit the search of files in $SEARCHDIR to those specified by --include.
I use double quotes rather than single quotes because of the shell variables. I would have thought this would cause the shell to expand the "*" but this doesn't seem to be the case.
I am trying to map the coordinates of a grid.
Code:
R=7 # number of rows (lines)

I am doing a mysql query with a bash shell script like:
mysql translator -u root --password=******** -e "SELECT word FROM tagalog ORDER BY RAND() LIMIT 1" | while read line; do
echo $line
So when I echo the value of $line I get:
word
magandang umaga
"word" is the name of the row in the table and maganda umaga is a randomly selected choice from the row. Is there a way i can remove the name of the row from the variable $line. With a result that will allow me to echo $line and output only the randomly selected entry in from the row e.g. magandang umaga
i have the following:
Quote:
echo %host%|sed "$s/.$//"
this would remove the Last character of the value assigned to the %host%. for example if my value is: abcd i get abc. but i am not able to assign the output. for example when i do
Quote:
set k=`echo %host%|sed "$s/.$//"`
after doing echo %k i get no output at the command prompt...!! whereas when i just type:
Quote:
echo abcd|sed "$s/.$//"
at the command prompt i get abc. maybe some other ways to Remove the Last character...?
I need to check whether a shell script variable contains non-zero numeric data to proceed. The variable should contain numeric values, but may in fact contain zeroes, blank space or nothing. So far, I have tried various combinations of:
Code:
if test $variable
then
if test $variable -gt 0
then
echo "good data exists"
else "no good data exists"
fi
fi
It partially works, but I get either "too many arguments" or "integer expression expected".
I want to get the last term of an unknown-sized text line, by usig the awk command. Is there any variable which points to the last term of a text line ? (obviously, y can obtain that term if i knew how many terms does the line have... i.e. awk '{print $12}' ; if we are talking about a 12-terms text line) I wonder if there is an option like $?, to get the last term.

I have two text file named 1.txt & 2.txt.
1. txt contains 5 laks of mobile number.
2. txt has 60 laks of mob no.
Situation is that I want to find and delete numbers in 2.txt which already in 1.txt. Any perl or bash script or any other way to get the work done.
I tried the following:
#! /bin/bash

do sed -ie "|^$NAME$|d" two.txt done

It works well with smaller file but it take very very long time even processing 10 thousand numbers.

I am bouncing a file across platforms (windows->solaris->mainframe), and the file is starting out with a "special" character (the registered trademark "circle R") in some of the records. This character is not in the EBCDIC character set on the MF, so it is unrecognizable. The MF developer I am working with asked if it is possible to replace the character with a specific hex value (AF) before it gets to the MF.
I was putzing around with sed, tr, etc. on the ksh command line, hoping to find an easy way to get one of them to substitute hex instead of ASCII. I have found that the usual shell utilities recognize the trademark character, so homing in on what to replace is solved. But I cannot get anything to actually substitute in the hex sequence I want. E.g. I was thinking something like...
>cat special_file | sed 's/R/AF/g'
But my version of sed does not seem to have hex "editing" capability.
I am beginner in this business of shell script and I have no idea how to do the following: I would like to replace the lines of my file that contains 'CFL=' by 'CFL=0.5'. Note that I want to replace the full line meaning

I have a big csv-file wich is not formatted very well. I clean it up with removing a lot of html etc, but some of the lines breaks where they are not supposed to.What I want to do is to check next line, if it starts with 'PX' I don't want to do anything, but if it does not start with 'PX' I want to merge the two lines. That is removing the newline character on line one and replace it with a space.Can this be done with sed? (or maybe with perl or something, but I'm more familiar with sed)I've been looking und the net to find a solution, but to no result.

Inside a loop i'm populating a string variable. Because csh doesn't have very good support for arrays I thought of doing this. I want to add a new line character to the end of the concatenation each time the loop iterates. Then at the end print this variable out.
I tried " and some resources said it was just a "". Neither work. What am I doing wrong?
