shell 判断文件夹是否存在,shell模糊判断文件是否存在

shell判断文件夹或文件是否存在。文件比较字符-e文件名为trueif文件名存在[-e/var/log/syslog]-dfilename为trueif文件名为目录[-d/tm-x判断对象是否存在且是否可执行-O判断对象是否存在且属于当前用户-G判断对象是否存在并属于当前用户组-nt判断file1是否比file2新["/data/file1"

#shelljudgeswhetherthefolderexists#Ifthefolderdoesnotexist,createafolderif[!-d"/myfolder"];thenmkdir/myfolderfi#shelljudgeswhetherthefileordirectoryexistsorhaspermissionfolder="/vaif["$var1"="$var2"];thenecho'var1eq$var2'elseecho'var1noteq$var2'fitodeterminewhether文件存在 #!/bin/shtoday=`date-dyesterday+%y%m%d`file="apache_$

shell判断文件或目录是否存在，如下：1.文件比较字符1-e文件名如果文件名存在，则为真2-d文件名如果文件名是目录，则为真3-f文件名如果shell命令判断文件或文件夹是否存在判断/data文件夹是否存在，orifit不存在，createif[!-d"/data/"];然后mkdir/dataelseecho"thefolderalreadyexists"fitodeterminewehetherthefileexists,exist

#shelljudgeswhetherthefolderexists#Ifthefolderdoesnotexists,createafolderif[!-d"/myfolder"];thenmkdir/myfolderfi#shelljudgeswhetherthefile,directoryexistsorhaspermissionfolder="/var/www/"shell:Determinethefolderexists,ifnot,createafoldernamedtestgridandcreateanewfilenamedtest.sh,内容为跟随！ /bin/bashif[!-dtestgrid];thenmkd

shell判断文件夹是否存在，下面小编将介绍我自己的简单方法。,createafolderif[!-d"/myfolder"];thenmkdir/myfolderfi#shellDeterminewhetherthefile,directoryexistsorhaspermissionfolder="/var/www/"
