For loop of shell scripts

There are many types of for loops in shell scripts, and a brief summary of the following is done today.

1. Cyclic Digital

#!/bin/bash for((i=1; i<=; i++));   do     Echo $ (expr31);  Done

 #!/bin/bash   for  i in  $ (seq  1  10  )   do  echo  $ (expr  $i \* 3  + 1   done  

#!/bin/bashfor in {1.. Ten }do    Echo $ (expr31);  Done

#!/bin/awk'begin{for (i=1; i<=10; i++) Print i}'

Results:

4 7 Ten  -  -  +  A  -  -  to

2. Loop string

#!/bin/bashfor in 'ls';   do     Echo file name\!  ;  Done

Result (output current file name):

for. SH

#!/bin/bashfor in $* ;   do   echo $i is input chart\!  ;  Done

Result (all current input parameters are output):

192 SH for. SH param1 param2 param3param1 is input chart! param2 is input chart! param3 is input chart!

#!/bin/bashfor in  F1 F2 F3;   do    Echo $i is appoint;  Done

Results (circular spaces separated by the character list):

192 SH for. SH F1 is APPOINTF2 are APPOINTF3 is appoint

#!/bin/bashlist="rootfs usr data data2"for in  $list;  do    echo  $i is appoint;  Done

Results (circular list):

192 SH for. SH Rootfs is appointusr is Appointdata are Appointdata2 is appoint

3. Path Lookup

#!/bin/forfile in/volumes/work/*; Do    echo $file is file path \!;d One

Result (loop to find current directory):

192: Shell-home xxx$SH  for.SH/volumes/work/bak_0_media isfilePath!/volumes/work/bak_0_text isfilePath!/volumes/work/apache-maven-3.5.3IsfilePath!/volumes/work/apache-tomcat-9.0.8IsfilePath!/volumes/work/chromedriver isfilePath!/volumes/work/git-repository isfilePath!/volumes/work/intellij-setting-files isfilePath!/volumes/work/justfortest isfilePath!/volumes/work/mavenrepository isfilePath!/volumes/work/pathfordownload isfilePath!/volumes/work/selenium-server-standalone-3.0.0. Jar isfilePath!/volumes/work/shell-home isfilePath!

#!/bin/bashforfile in $ (ls /volumes/work)do     echo $filefile path \! ;  Done

Result (the result of cyclic LS removal):

192: Shell-home xxx$SH  for.SHBak_0_media isfilePath!Bak_0_text isfilePath!Apache-maven-3.5.3IsfilePath!Apache-tomcat-9.0.8IsfilePath!Chromedriver isfilePath!git-repository isfilePath!IntelliJ-setting-files isfilePath!Justfortest isfilePath!Mavenrepository isfilePath!Pathfordownload isfilePath!Selenium-server-standalone-3.0.0.
