Programming :: Write A Bash Script That Sources Another Bash Script?
Jan 29, 2011
I am trying to write a bash script that sources another bash script. Essentially, I need a few lines to check to see if a certain variable is set. If not, I set it manually, and then source a scripts with that variable in the path. I wrote a test script to try it, but for some reason the last line does not work. Here is what I wrote:
#!/bin/sh
source ~setupdir/setup.shrc #just a test, this line works
echo ${#SETUP} # prints 0 if setup is not set, which it isn't
if [ ${#SETUP} -eq 0 ]
then
SETUP="~setupdir"
fi
echo $SETUP # prints ~setupdir
I create a bash script that writes another bash file. But in the generated bash file I want to write a bash command in the file and not executing it.Here's my bash file:
Code: #!/bin/bash cat > ~/generateGridmix2data.sh << END
I have been looking for a script example of reading and writing to the parallel port's data, status, and control registers using bash. I see it done in pascal, tcl, etc. but nothing in bash.

I think the problem has to do with modifying PS1 inside the bash so i tried this:
Code: echo `export PS1="[e]1;u@h:wa]${debian_chroot:+($debian_chroot)}u@h:w$ "` and it still didn't work.
In my tmp directory some logs are creating continue (with name logs.txt1, logs.txt2 up to 245). Some times these logs are creating continue within 1 or 3 second gap, now I want to write a bash script that continue monitor the tmp directory and if any time logs create simultaneously within 1 or 3 section gap it will alert me..( generally logs are create with the gap of 5 or 10 minutes duration or some time after one hours )
I have a bash script that checks for contents in a folder every 15 seconds and then acts on it's contents. This works great for the average size file however on very large files it starts acting on the file before it's completely written. Is there a facility in bash shell to get a file complete signal or such? here is trigger to launch a larger script.
Code:
#!/bin/sh while true do $HOME/bin/hpgl.sh >/dev/null 2>&1 &
I'm planing to write a bash script that will make some web stats reports and I'm stuck on beginning because I don't know how can I read a directory content, put everything in a variable, compare the variable value with current date and go further.More specific ...
I have /var/apache/log/. Here I have access logs on date ( like access.log.24.06.2010.gz and so on ).
How can I do to automatically zgrep (in a bash script) last day .gz ??
I have a folder of 2 many files that the old ls just hangs.
I am trying to write some log files such as;
I don't mind doing one at a time, but I am just playing and even getting the listing I am not getting the date stamp, I have the following;
That does create the file, but all the files look like this;
So basically it's just sticking that ls inside the log file and not actually running the ls, so how can I use the above type to get files just created per year?
I write a bash script to time some downloads from a server using ftp connection. ( something like: "time ftp 'options' ) I need to count the time for a list of files in a loop and output the result in a file.
I'm trying to write a bash script program in the Linux command terminal that will write to a fellow user and then continue reading down the program. this is what i have (kind of explains the idea too):
#!/bin/sh
clear echo "this is before the write command" write jcummins this message should go to jerry echo "the message didn't send and this string will not appear" echo "it appears it has stopped at the write command"
I would like to know how do I print the line # in a script. My requirement is, I have a script which is about ~5000 lines long. If there are any errors happen I just exit. And I would like to add the line # of the script where the error happened.
Code: #!/bin/bash trap "echo 'you got me'" SIGINT SIGTERM # to trap ctrl+c echo "Press ctrl+c during 5 sec loop" for ((i=0;i<5;i++)); do
[Code]...
How come code behaves normally and stops when ctrl+c signal is caught and resumes, but after I use at least one timeout read in the code it looks like, if signal is caught again it doesn't pause the execution but skips the loop. If you remove -t (timeout) option from the read, both loops look the same!
Now in my bash script, I want to get the output /home/user instead of $HOME once read. So far, I have managed to get the $HOME variable but I can't get it to echo the variable. All I get is the output $HOME.
I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?
I think it would be better to count the len and remove 3 chars to right to get the extension, but it can be macintosh filenames with have 4 chars for extensions.
I need to to write a bash script using an If...Then...Else statement that will accept a day of the week from the command line what do I do or where do I go.
I have started using Ubuntu and I have to add a large number of users, over a thousand, using a Bash Script. I also have to give them a password. Do you create a text file first.

I've been looking for how to set this up in bash with no luck so far. I can change what file the history log is written to, and how much history is saved. But it only writes the saved part when bash exits. Instead, I'd like to have bash write that file continuously as each command is entered (and maybe also do an fsync(2) to flush it to disk). That way I can see the command I crashed the box with Anyone know the magical incantation for that?
But there appears to be nothing that I can find there, in the man page, or other searches, that suggest it even can do continuous.
I mean codes on how to write a bash script for locate file. E.g: This utility shows you all files and directories that have a specific substring in the name. Press '?' for help, 'q' for quit or enter your search terms:

Are you sure you want to see all of those? [Y/n] n Press '?' for help, 'q' for quit or enter your search terms: Sorry, you didn't enter any search term. Press '?' for help, 'q' for quit or enter your search terms: q

I'm trying to write a bash script that gets the list of files in a directory and puts them into a variable, then checks each entry and outputs them as follows:
item1 is a FILE item2 is a DIR item3 is a DIR etc etc.
