[英]BASH storing grep output into variable or array
I have two arrays: one is an array of CPU numbers and the other is an array of server names. 我有两个数组:一个是CPU编号的数组,另一个是服务器名称的数组。
What I'm doing is searching a file to spit out the server name with the CPU number on the same line. 我正在做的是搜索文件以在同一行上吐出带有CPU编号的服务器名称。
You can see the code below: 您可以看到以下代码:
#!/bin/bash
cpu=("Atom" "Q8200" "Q9300" "Q9550" "i5" "i7" "X3440" "E3 1230" "Dell 860"
"Dell r410" "Dell R200" "E5645" "E5504" "Dell 1950"
"Dell 2950 Dual QuadCore Xeon E5420")
tknum=("tk676" "tk619" "tk20013" "tkc676" "tk74001")
for i in "${tknum[@]}" #being loop through tk numbers
do
temp=$(grep -i -m 1 "$i" /home/jeremysd/public_html/servers.txt) #return line tknumber is on and store in variable
#echo "$temp"
echo "$i" #Print out the tk number
for j in "${cpu[@]}" #begin loop through cpu numbers
do
echo "$temp" | grep -io "$j" #Return CPU number
done
done
Now this works and places the information out like this: 现在这可以正常工作并将信息放置如下:
sh array_test.sh
tk676
Q9550
tk619
Dell R200
tk20013
dell R410
tkc676
Q9550
That shows the server name and then CPU under it. 这将显示服务器名称,然后显示其下的CPU。 However, I want it to be comma separated so that I can import it into a database
但是,我希望将其用逗号分隔,以便可以将其导入数据库
e.g:
tk676,q9550
Now, my thinking was to store the CPU type in a temporary variable and then echo it out, but doing so causes many blank lines to be entered into the string. 现在,我的想法是将CPU类型存储在一个临时变量中,然后将其回显,但是这样做会使许多空白行输入到字符串中。
The loop through the CPU type becomes: 通过CPU类型的循环变为:
for j in "${cpu[@]}" #begin loop through cpu numbers
do
temp1=$(echo "$temp" | grep -io "$j") #Return CPU number
echo $temp1
done
The results are below and show extra blank lines. 结果在下面,并显示额外的空白行。 Anybody have any idea on how to store the CPU variables in a string or array without all the extra spaces being added?
有人对如何在不添加所有额外空格的情况下将CPU变量存储在字符串或数组中有任何想法吗?
sh array_test.sh
tk676
Q9550
Check for an empty result: 检查结果是否为空:
if [ -n "$temp1" ]
then echo "$temp1"
