So how about my question? How to pass the array as argument to the function?
:):)

Hi, guys

I just wanted to sort the elements of an array ascendingly.
I know the following code does work well:

array=(13 435 8 23 100)
for i in {0..4}
do
j=$((i+1))
while [[ $j -le 4]]...

Yes! I got it.

I got you and it works now. And if I use ((2 < 10)) to check the condition of loop, that works well too. Thx!:D

Hi, guys
Here is my script and it's an imaginary script to recast a string randomly.

#!/bin/bash
# scriptname: recast_string
# purpose: recast a string randomly like this "abc123" --> "21a3cb"...

Assuming that you have three scripts "a.sh" "b.sh" "c.sh" and there are three log file "a.log" "b.log" "c.log", and here is my opinion:
Execution of b.sh depends on whether the last successful...

I suggest you give us some clue about input and desired output.

diff -c file1 file2 | gawk '/^+/ {print $2}' >> file_diff
However, I feel it's wired. Maybe I have no idea about your real need.

My script is below:

#!/bin/bash
now_time=$(date +%Y-%m-%d\ %H:%m:%S)
echo "***Start at: $now_time***"
i=0
while [ i -lt 16 ]
do
if [ ! -e /path/to/filename ]
then
...

I thought it seemed kind of customary:rolleyes:

I have a question.
e.g.
Assuming that there are 10 lines in the file_A and 5 lines in the file_B, and the content shown below:
file_A

file_B


please tell me what's your desired output?

I have one question.
Let me give some example according to your script.
There is one file "index.html" in the directory "/home/web/aaa/bbb"
What the script does is :
1. assign "index.html" to the...

This is your file:

and this is the script:

#!/bin/bash
# scriptname: check_01
# purpose: read the file "sample" line by line and check existence of files
# and directories

while read line...

I don't get the exact content of svn log file. So please let me assume that every line starting with "M" represents modification, every line starting with "A" represents adding, every line starting...

cos the period punctuation "." in the double quotes can represent any single character. You should use the escape sequence to get its original meaning.
like this: "\\." or /\./

Thanks, I got it. Your code is more efficient.

Hi, give you a simple example, hope to help you.
Assuming there are two files named "file1", "file2" in a specified directory, shown below:
[root@centostest2 20130619]# ls -ls
total 4
0...

gawk 'BEGIN{FS=OFS=","}NR==FNR{a[$1]=$2}NR>FNR{print $0,a[$2]}' file2 file1
100,A,1
200,B,2
300,C,3
600,B,2
400,C,3

Hi, guys,
The content of file is below （from <UNIX® Shells by Example Fourth Edition>):

Cool! Thanks!:D

Hi, Guys,
There is one question about AWK format. Here is the code:
gawk -F: '/^Dan/ {print "Dan's phone number is ",$2}' lab3.data

An syntax error will come out because the quote mark between...

I think you are right.
What about my third question?~~

Hi, guys,
With some guys' help, I made a shellscript used to create new users(attached at the bottom).
I have some questions:
a). I need to prompt users to enter their password in my script, but...

OMG!
I got you! Thanks

Yes, your code is simple. However, it's not good if the absolute path of directory contains metacharacters. So I just did my best to avoid it happened.
