Variable Assignment Problem Solving Procedure : Echo ${sho} |grep 1, named a1=\$1 Echo ${sho} |grep 2, named a2=\$2 Echo ${sho} |grep 3, named a3=\$3 Echo ${sho} |grep 4, named a4=\$4 Echo ${sho} |grep 5, named a5=\$5 6, named a6=\$6 echo ${sho} |grep Echo ${sho} |grep 7, named a7=\$7 If the input variables containing 1 sho, a1=$1. If the input variables containing 2 sho, a2=$2 Renumbered. If sho=347 operations, Echo "\$a1=" $a1 "\$a2=" $a2 "\$a3=" $a3 "\$a4=" $a4 "\$a5=" $a5 "\$a6=" $a6 "\$a7=" $a7 $a1= $a2= $a3=$3 $a4=$4 $a5= $a6= $a7=$7 Was correct. Question : it hopes to achieve recycling. For i in 1 2 3 4 5 6 7 Do Echo ${sho} |grep $i, named a${i}=\$${i} Done It is obviously not acceptable and tried echo ${sho} |grep $i, named eval a${i}=\$${i} too. Solving Thank you. Sorry, made a two times Top about Eval a$i=\\$\$i [ Closed window ]
