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 :: 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:"

Programming :: Shell: Give A Range Argument To 'for'

Feb 20, 2010

Feel free to just link to another thread where this is (pre)solved; I can't search the forum for the word "for," because it's too short (or maybe the search engine dislikes prepositions).

Is there a way to give the 'for' command a range? Here's what I mean:

Code:
#for i in (1-5); do echo $i; done
Certainly, meat space user; I understand exactly what you're thinking.
1
2
3
4
5
True, I realize I could use

Code:
COUNT=1 ; while [ $COUNT -lt 6 ]...

...but if I can avoid the extra preparatory step I'd prefer to do so.

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"

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.

CentOS 5 :: Pass Shell As Command Line Argument When I Ssh To An Account

Jan 25, 2011

I want to have a choice or more preferable pass shell as command line argument when I ssh to an linux account.i.e. If John logs in to account "zzz" on server "abc", by default definition of account "zzz" n server "abc" he get csh.But Sally desires that when she logs in to account "zzz" on server "abc", she needs the login shell to be ksh,and Rick wants bash when he logs in to account "zzz" on server "abc".What is the most non-intrusive / easiest way to achieve this? Each user can set their preference on ssh command line or create a simple alias by each shell, but not sure how to do this.
