AWK语法错误

AWK语法错误

我试图找到具有给定扩展名的所有文件,并 awk 结果并将其附加到 all.txt 中。

set -xe

EXT="${1}"
TYPE="${2}"
COMP="${3}"

find -iname \*.${EXT} -print0 | xargs -0 ls -l --time-style="+%b %Y" | awk '{print $NF,$3,$5,$6,$7}' OFS="\t" > ${EXT}.txt
awk -vextension="${EXT}" -vfiletype="${TYPE}" -vcompress="${COMP}" -vOFS="\t" '{print $0, extension, filetype, compress}' < ${EXT}.txt >> all.txt

我能够从 find 命令获取输出,

.fielename.gz   Jason   197025960   May 2018

但是,我从 awk 命令中收到此语法错误,

+ awk -vextension=gzip -vfiletype=gz -vcompress=compressed '-vOFS=\t' '{print $0, extension, filetype, compress}'
awk: {print $0, extension, filetype, compress}
awk:                     ^ syntax error

尝试extension用其他名称替换变量名称,例如ext; in gawk,extension是关键字/内置。

$ gawk 'BEGIN{print extension}'
gawk: cmd. line:1: BEGIN{print extension}
gawk: cmd. line:1:                      ^ syntax error
$ gawk 'BEGIN{print ext}'  # OK
^D
$ gawk -vextension=gzip 'BEGIN{print extension}'
gawk: fatal: cannot use gawk builtin `extension' as variable name
