这些田地用<条码>取代条码>。 每个领域($i
- f或 field number i
<>em>)可保存到一个临时变量f
。 然后,外地内容被取代。 本记录可以更正。 利用临时价值将外地恢复到以往的价值。
如果使用这一数据,可能会更容易跟踪:001 002 003 004
。 之后,产出将考虑:
100 002 003 004
001 100 003 004
001 002 100 004
001 002 003 100
此处为使用<代码>的印本<>。
data= 001 002 003 004 # 或 000 000 000 000
f或 i in {1..4}; do echo "$data" | sed "s/<[0-9]{3}>/100/$i"; done
或
count=$(echo "data" | $wc -w)
f或 ((i=1;i<=count;i++)); do echo "$data" | sed "s/<[0-9]{3}>/100/$i"; done
或 Bash without any external utilities:
data=(001 002 003 004) # use an array
count=${#data[@]}
f或 ((i=0;i<count;i++)); do f=${data[i]}; data[i]=100; echo "${data[@]}"; data[i]=$f; done
或者许多其他可能性。
