What am I missing here? Below is a sample of the output. $ ./test.sh asdf 1 te...
Hi! I am writing some Java code that needs to be able to write a pidfile on Unix-like as well as windows machines. On the unix machines I write out a bash shell script that contains something like this command 1>/dev/null 2>&1 & echo $! > pidfile It executes a command, redirects all output into nirwana and puts command into the backg...
I'm writing a shell script that opens a file and needs to find a tag like ##FIND_ME##. The string I'm searching for is a constant (and there is only ever one instance of it.) Once I locate that string, I need it to start a new search for a different string from that point forward. My *nix skills are a little rusty, should try to imple...
I need to run a complex series of commands in PHP, and I'm not sure about exactly how to do it. We have two executables we need to work with: generate to create a fruit basket. This generates an XML file. peel to peel a fruit by identifier. Generates a long string. There are basically 5 steps: First, system("generate ... > fruits.x...

I have a file folders.txt one two three four ... that has a list of folder names. [one, two, three and four are names of folders]. Each of these folders has a number of files of different types (different extensions). I want a list of all the files in all the folders of one particular extension, say .txt. How should my shell script ...
I just came to know that .sh files don't use set and spaces around = are not allowed, while this is allowed in a .csh file. Is there some place that you can point me to where I can find all these minor differences? ...

This is a little thing that bothers me every now and then: I write a shell script (bash) for a quick and dirty job I run the script, and it runs for quite a while While it's running, I edit a few lines in the script, configuring it for a different job But the first process is still reading the same script file and gets all screwed up. ...
From Epigrams in Programming by Alan J. Perlis: 22. A good system can't have a weak command language. What does this mean? What are good examples of this principle? Where can I learn more on how to implement a command langauge that meets this criteria? ...
an Unix shell script with only purpose - count the number of running processes of qmail (could be anything else). Easy thing, but there must be some bug in code: #!/bin/bash rows=`ps aux | grep qmail | wc -l` echo $rows Because echo $rows always shows greater number of rows (11) than if I just count rows in ps aux | grep qmail T...
Let's say that we have a Python script do.py and we want to be able to call it without extension, like do or ./do. If we rename the file from do.py to do and assure we have a valid shebang line it will work for all platforms but Windows. On Windows there is no way of executing file without extension. On Windows, if we keep the origina...
My goal is to use a script that will install an executable file on Linux (Busybox variant). The target file should run when the computer starts, so in the rc.sysinit file, I'll have a line like the following: /usr/bin/foo & Now, when I run the install script, that line may or may not already be present (depending if the file had been ...
Hi all, I am trying to get file extension for a file in shell script. But without any luck. The command I am using is file_ext=${filename##*.} and file_ext = $filename |awk -F . '{if (NF>1) {print $NF}}' But both of the commands failed to put value in variable file_ext. But when i try echo $filename |awk -F . '{if (NF>1) {print...
Hi I want my script to define an empty array. array values should be added if predefined condition gets true. for this what i have done is declare -a FILES file_count=0 if [ "$file_ext" != "$SUPPORTED_FILE_TYPE" ] ; then echo "$file_ext is not supported for this task." else $FILES[$file_count] = $filename file_c...
i have a bash script that builds a string to run as a command the script: #! /bin/bash matchdir="/home/joao/robocup/runner_workdir/matches/testmatch/" teamAComm="`pwd`/a.sh" teamBComm="`pwd`/b.sh" include="`pwd`/server_official.conf" serverbin='/usr/local/bin/rcssserver' cd $matchdir illcommando="$serverbin include='$include' server...
I am trying to include this du -s *|awk '{ if ($1 > 3000) print }' in a shell script, but I want to parameterize the 3000. However, since the $1 is already being used, I'm not sure what to do. This was a total failure: size=$1 du -s *|awk '{ if ($1 > $size) print }' How can I pass a parameter in place of 3000 in the first script ab...
Here's one for the bash-fu wizards. No, actually, I'm just kidding, you'll all probably know this except for me.. I'm trying to create a backup shell script. The idea is fairly simple: find files in a certain folder, older than 7 days, tar/gzip them to another directory, and remove them. The problem is, I'm not sure if I'll have enough ...
I have a list of ~900 domains that I need to set up on a linux/apache server. It would be absolutely brutal to create all of the users/groups/vhosts by hand. Does anybody know of a resource that I could use to automate this? I guess the script should do these actions: Read text file line by line in to array For each item in array: User...
