本文实例讲述了Linux bash删除文件中含“指定内容”的行功能。分享给大家供大家参考，具体如下：
#!/bin/sh# 功能: 删除文件中含"指定内容"的行# 运行方式: ./dline.sh c.log ==> 产生输出文件: c.log0array=( "rm -f lvr_3531_pf_new" "arm-hisiv100-linux-gcc " "In function " "excess elements in array initializer" "warning: multi-line comment" "embedded '\0' in format" "__NR_SYSCALL_BASE" "this is the location of the previous definition" "dereferencing type-punned pointer will break strict-aliasing rules" "differ in signedness" "but argument is of type" "implicit declaration of")if [ $# -lt 1 ];
then echo "Usage: $0 <logfile>" exitfifile="$1"0cp -f $1 $filefunction deleteLine(){
sed "/$1/d" $file > tmp mv -f tmp $file}
wc -l $filefor line in "${
array[@]}
"do if [ ${
#line}
-gt 0 ] && [ ${
line:0:1}
!= "#" ];
then deleteLine "$line" fidonewc -l $file
运行情况：
[feng@bash #69]$./dline.sh c.log556 c.log063 c.log0[feng@bash #70]$
希望本文所述对大家bash shell学习有所帮助。
