我正在使用bash腳本來grep文件,然後運行perl命令。我知道這些命令自從我使用它們以來就工作了,但我似乎無法讓它們爲bash腳本工作。我將不勝感激任何幫助。bash腳本+ grep + perl命令
當我輸出$ 1等等它有值,但是當我輸出grep命令與他們在裏面。我得到的文件找不到或空白的空格。
#! /bin/bash
usage()
{
echo "Usage: $0"
echo $'\a'Supply 4 arguments
echo $0 arg1 arg2 arg3 arg4
echo "1. search parameters for bookmarks"
echo "2. What file to grep"
echo "3. file to temporaly store results"
echo "4. what file to store the final version"
exit 1
}
main()
{
# if [ "$#" -lt "4" ]
# then
# usage
# else
echo "beginning grep"
grep -ir "$1" "$2" >> "$3"
echo "grep complete"
# echo "beginning perl command"
# perl -0ne 'print "$2\n$1\n" while (/a href=\"(.*?)\">(.*?)<\/a>/igs)' "$3" >> "$4"
# echo "perl command complete"
# echo "done"
# exit 1
# fi
}
main
echo $0
echo $1
echo $2
echo $3
