Programming :: Shell Scripting / Create A Shell Script Similar To Ls?

Jun 5, 2011

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.

Code:
if [ $# -eq 0 ] ; then
d=`pwd`
for i in * ; do
if test -d $d/$i ; then
echo "$i:"

General :: Create A Menu Box Window Using Dialog In Shell Scripting

Feb 3, 2010

I am using Linux on my system. I don't have gui for my system, only console is there.

I have some task to create a menu box window using dialog in shell scripting.

I have to take input from user & save it in a file.

But this should like html form as e.g.

Name - .....................
email id - ..................
phone - ......................
location - ...................

Submit Cancel

Such window should be displayed on console using dialog & then user will enter his information there as Name,email id, phone,etc & submit it, then it gets saved to a file. Here submit & cancle are buttons. I have to do it in bash shell scripting. Or give me some examples like the above with shell script code.

Fedora :: Create A Shell Script File With Two Functions - Bash Scripting & /etc/bashrc

Oct 6, 2010

how come I can create a shell script file with two functions, I can execute the file, but when running declare -f, the functions are not on memory, and when invoking the function bash returns invalid. In the other hand, I can copy & paste the two functions at the end of my /etc/bashrc file.... then I can called the function by name.... and the commands within that function run on my session. here is a print of all my bash packets:

[Code]....

Does Fedora has restrictions on shell scripting? I haven't touch bash in seven years, so if things have change on it I'm behind on it, and sorry for my ignorance.

Programming :: Compare Two Files Using Perl Or Shell Scripting?

Mar 8, 2010

I want to compare the following two tab-delimited .txt files (both were subsets of the original files) by comparing Columns 3 and 4 simultaneously. It is easy to compare C3 because both C3s are just numbers. But how to compare C4s?Basically, in File1, "G,G" = G in File2, "C,C" = C in File2, "A,A" = A in File2, "T,T"= T in File2.In File2, A/T in Column4 just equals "A,T" or "T,A" in Column4 of File1. C/T in Column4 just equals "C,T" or "T,C" in Column4 of File1, and etc.

File1:

C1C2 C3C4
ih509rs12345467244750"G,G"
ih499rs6049687244911"C,C"
ih508- 7244977"A,A"

Mar 11, 2011

I have a QNX machine with a slinger webserver running on it. With a cgi script i'm trying to do the QNX cksum call and compare it's output value with a fixed output.

Programming :: Shell Scripting: Scraping Public IP And Emailing?

Jul 3, 2011

so I wrote a simple script to scrape whatsmyip.org for my public IP address and then email it to me if it has changed. I set this up as a cron job ever 30mins.the problem is, it works for about 18 hours and then will have an issue where it says "line 33: [: too many arguments" Which line 33 happens to be my if statement. Now like I said it works fine for about 18 hours, i run the script with 2>&1 to a .out file so i can see what its doing...this is the output of the .out file, the "xxx" does actually show the ip.."PHP Code:

xxx.xxx.xxx.xxx
already in file
xxx.xxx.xxx.xxx

Programming :: C-shell Scripting Syntax Error When Defining Two Variables A1 And A2

Apr 5, 2011

I am trying to modify a script for research purposes and am having difficulty here as I have little prior experience with C-shell scripting.

The script looks as follows (it includes tcl commands like runFEP that you can ignore)

#!/bin/bash

for ((old=1, new=2; old<=4; old++,new++))
a1=${old}%50
a2=${new}%50
do
cat > input${new}.conf <<EOF
${a1}
code....

My question: I keep getting a syntax error when defining my two variables a1 and a2. I essentially need these variables to be
a1 = value of variable old divided by 50
a2 = value of variable new divided by 50

Programming :: Shell Scripting For Accepting Input From Different Directories Automatically

Nov 6, 2010

The two shell scripts (t1prog and t2prog) are given below they are working fine. The input for the first program is 't1.det' and for second program is 't1.rnaml'. These two input files are in 'dir1' folder. I am executing the shell like 'sh t1prog > t1out' and 'sh t2prog > t2out' from this directory only. Then I am executing a java program 'java RNA'; for this, t1out and t2out are input files used in the program and I am getting the final output on screen.

The input files 't1.det' and 't1.rnaml' are in different folders with same name and with different values. Each folder specifies one gene sequence input files.

In mfold directory there are 5 directors and each directory contains these input files as shown below
cd mfold
dir1 dir2 dir3 dir4 dir5
cd dir1
t1.det t1.rnaml

[Code].....

for inputs in different directories and executing these and redirecting the final ouput after executing 'java RNA' statement to a file is needed.

Programming :: Shell Scripting - Value Disappears Depending On Argument Order

Mar 21, 2011

Examples:
Code:
$ ./test.sh -a -c 2
operator is -gt
remcount is
^ value missing!

Code:
$ ./test.sh -b -c 2
operator is -lt
remcount is
^ value missing!

Yet when "-c" is the first argument, its value is present:
Code:
$ ./test.sh -c 2 -b
operator is -lt
remcount is 2
What could I do to ensure the value of "-c" is picked up regardless of the argument order?

Programming :: Bash Scripting - Display Real Name From Username Logged In + User Processes?

this is my script:

Programming :: Bash Scripting - Taking User Input And Adding It To A Particular Area Of A File?

Jan 12, 2010

in bash scripting...say I want to take the input from a user via a question...I would do this:

Quote:

#!/bin/bash

echo "How large do you want this partition to be in GB (enter only the number)?" read PART_SIZE echo "You want your partition to be $PART_SIZE GB" But I don't want to echo it back to the screen, I want to add it to the content of /etc/fstab. I have been mucking around with sed to find the tmpfs partition in /etc/fstab and add the partition size attribute (this is to use the onboard RAM as a volatile partition)...but am not having any luck...

The portion of /etc/fstab that uses /dev/shm for the tmpfs partition is:

tmpfs /dev/shm tmpfs defaults 0 0

So, if a user says "24" GB to the answer (from above), how do I get it to automatically add that value to the tmpfs partition line in /etc/fstab? So it would look like:

tmpfs /dev/shm tmpfs size=24g,defaults 0 0

I understand that I would also have to come up with a way to put "size=XXg", which I could do with a copied over generic file before this action...then the script would have to find "XX" and replace it with the user's figure...

Programming :: Bash Scripting With Sudo / Password Prompt And Accepting User Input?

Jul 30, 2011

I'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:

Code:

zip -r example * -e

now how would I get the script to insert my wanted password.
