拒绝labor 拥抱脚本~高效替换所有文件中字符串的Shell
使用场景： Linux或者Unix系统中，先查看下某个目录下所有文件列表：
tsadmin@tslnx10:~/com.ibm.rfidic.test.data/queries/set1.1/expected> ls CVS FVT_QG_EPCISCHG_0008_Expected_Response.xml FVT_QG_EPCISCHG_0019_Expected_Response.xml FVT_QG_EVENT_0001_Expected_Response.xml FVT_QG_EVENT_0002_Expected_Response.xml FVT_QG_EVENT_0003_Expected_Response.xml FVT_QG_EVENT_0005_Expected_Response.xml FVT_QG_EVENT_0009_Expected_Response.xml FVT_QG_EVENT_0020_Expected_Response.xml FVT_QG_EVENT_0025_Expected_Response.xml FVT_QG_EVENT_0030_Expected_Response.xml FVT_QG_EVENT_0031_Expected_Response.xml FVT_QG_EVENT_0035_Expected_Response.xml FVT_QG_EVENT_0038_Expected_Response.xml FVT_QG_EVENT_0041_Expected_Response.xml FVT_QG_EVENT_0045_Expected_Response.xml FVT_QG_EVENT_0048_Expected_Response.xml FVT_QG_EVENT_0056_Expected_Response.xml FVT_QG_EVENT_0060_Expected_Response.xml FVT_QG_EVENT_0065_Expected_Response.xml FVT_QG_EVENT_0076_Expected_Response.xml FVT_QG_EVENT_0077_Expected_Response.xml FVT_QG_EVENT_0094_Expected_Response1.xml FVT_QG_EVENT_0094_Expected_Response2.xml FVT_QG_EVENT_0101_Expected_Response.xml FVT_QG_EVENT_0103_Expected_Response.xml FVT_QG_EVENT_0111_Expected_Response.xml FVT_QG_EVENT_0112_Expected_Response.xml FVT_QG_EVENT_0118_Expected_Response.xml FVT_QG_EVENT_0130_Expected_Response.xml FVT_QG_EVENT_0131_Expected_Response.xml ................................. |
如果这些文件里都包含abc字符串，我想把他们全部替换成123，手工一个一个改，真是费力不讨好啊~ 不如写个脚本完成这个工作。
#!/bin/bash if [ $# -ne 2 ];then echo "usage: replaceKeyword.sh " exit 1 fi SEARCH_KEYWORD=$1 REPLACE_STRING=$2 CURRENT_DIR=`pwd` echo "Replacing $SEARCH_KEYWORD to $REPLACE_STRING in all files under $CURRENT_DIR starts ..." for i in `ls` do grep $SEARCH_KEYWORD $i > /dev/null if [ $? -eq 0 ]; then echo "Replace keyword in $i" sed "s/$SEARCH_KEYWORD/$REPLACE_STRING/g" $i > tmp mv tmp $i rm -f tmp fi done echo "Finished." |
实战下：我们希望把所有的<eventTimeZoneOffset>Z</eventTimeZoneOffset>替换成<eventTimeZoneOffset>+00:00</eventTimeZoneOffset>(注意要带双引号去除Shell对于>的特殊对待)
