[英]Awk - Adding specific number of spaces between columns
My input file has columns which are space evenly like so: 我的输入文件具有均匀分布的列,如下所示:
X a b C D
How do I use awk to specify the number of spaces between the columns such that I get something like this: 我如何使用awk指定列之间的空格数,以便得到如下内容:
X a b C D
I know how to count the spaces between the columns using awk, I just don't know how to add those spaces in order to get the layout I want. 我知道如何使用awk计算列之间的间隔,我只是不知道如何添加这些间隔以获取所需的布局。 Any suggestions?
有什么建议么?
with awk
与
awk
$ echo "X a b C D" | awk '{printf "%-6s%-2s%-5s%-9s%s\n", $1,$2,$3,$4,$5}'
X a b C D
or with printf directly 或直接与printf
$ echo "X a b C D" | xargs printf "%-6s%-2s%-5s%-9s%s\n"
X a b C D
This is where printf comes in handy: 这是printf派上用场的地方:
$ echo "X a b C D" | perl -lane 'printf "%-6s%-2s%-5s%-9s%s\n", @F'
X a b C D
Adjust the field widths as required. 根据需要调整字段宽度。
