[英]execute mailx using shell script
I am trying to run the below script. 我正在尝试运行以下脚本。
val = `wc -l /home/validate.bad | awk '{print $1}' | tail -n1`
valCount = `wc -l /home/validation.txt | awk '{print $1}'`
if [ "$val" -gt 1 ] && ["$valCount" -gt 1]
then
mailx -s "Validation failed" -r xyz@abc.com xyz@abc.com<<-EOF
Hi ,
Validation has failed. Please check.
EOF
elif [ "$valCount" -gt 1 ]
then
mailx -s "Validation pass" -r xyz@abc.com xyz@abc.com<<-EOF
Hi Team,
Validation success.
EOF
fi
But I am getting this error. 但我收到此错误。
Error:
val: comand not found
valCount: command not found
line 3[: : integer expression expected
You can't have spaces around =
: =
周围不能有空格:
val = `wc -l /home/validate.bad | awk '{print $1}' | t` # wrong
and should have been 并且应该是
val=`wc -l /home/validate.bad | awk '{print $1}' | t`
or preferrably 或最好
val=$(wc -l </home/validate.bad)
#`..` is legacy , $() supports nesting, one good reason to go for it
# You use awk and tail uselessly
Also 也
["$valCount" -gt 1]
should have been 本来应该
[ "$valCount" -gt 1 ] # mind the spaces for the test constructie
# [spaceSTUFFspace] is the correct form
Sidenote 边注
You may use [ shellcheck ] to check your scripts. 您可以使用[shellcheck]检查脚本。
