我必须创建一个包含 85 个条目的巨大文件,格式如下:
user_dept1=$( while read -r x && read -r y <&3; do echo " model: $model_1 user: $x department: $y License_Used: $p_out1"; done < /home/user_files/out1.txt 3</home/dept_files/dep1.txt | ts '%Y-%m-%d %H:%M:%S')
user_dept2=$( while read -r x && read -r y <&3; do echo " model: $model_2 user: $x department: $y License_Used: $p_out2"; done < /home/user_files/out2.txt 3</home/dept_files/dep2.txt | ts '%Y-%m-%d %H:%M:%S')
依此类推,直到 user_dept85
user_dept85=$( while read -r x && read -r y <&3; do echo " model: $model_85 user: $x department: $y License_Used: $p_out85"; done < /home/user_files/out85.txt 3</home/dept_files/dep85.txt | ts '%Y-%m-%d %H:%M:%S')
因此下面的字符串每次都会从 1-85 重命名:
user_dep1 - user_dept85
$model_1 - $model_85
$p_out1 - $p_out85
out1.txt - out85.txt
dep1.txt - dep85.txt
答案1
您只想生成 85 行代码?
for a in {1..85}
do
echo "user_dept$a=\$( while read -r x && read -r y <&3; do echo \" model: \$model_$a user: \$x department: \$y License_Used: \$p_out$a\"; done < /home/user_files/out$a.txt 3</home/dept_files/dep$a.txt | ts '%Y-%m-%d %H:%M:%S')"
done > resulting_code
诀窍是确保遵守引用。因此$
and "
" 字符需要被引用为\$
and\"
结果输出的前 3 行:
user_dept1=$( while read -r x && read -r y <&3; do echo " model: $model_1 user: $x department: $y License_Used: $p_out1"; done < /home/user_files/out1.txt 3</home/dept_files/dep1.txt | ts '%Y-%m-%d %H:%M:%S')
user_dept2=$( while read -r x && read -r y <&3; do echo " model: $model_2 user: $x department: $y License_Used: $p_out2"; done < /home/user_files/out2.txt 3</home/dept_files/dep2.txt | ts '%Y-%m-%d %H:%M:%S')
user_dept3=$( while read -r x && read -r y <&3; do echo " model: $model_3 user: $x department: $y License_Used: $p_out3"; done < /home/user_files/out3.txt 3</home/dept_files/dep3.txt | ts '%Y-%m-%d %H:%M:%S')

我不确定ts
对你有什么作用,但如果你可以使用 bash 数组而不是按名称编号的变量,这应该可以满足你的要求:
#!/bin/bash
for n in {1..85}
do
x=$(</home/user_files/out${n}.txt)
y=$(</home/dept_files/dep${n}.txt)
user_dep[$n]=$(echo " model: \$model_${n} user: $x department: $y License_Used: \$p_out${n}" | ts '%Y-%m-%d %H:%M:%S')
done
# and show results
for n in {1..85}
do
echo user_dep${n} = ${user_dep[$n]}
done
