linux - run cat command for all the files in the directory given in argument of the script file and out put with the name given as second argument -


i run following code concatenating files in directory given argument script file in bash

for in $*       cat $* > /home/christy/documents/filetest/catted.txt  done

this produce error

cat: /home/christy/documents/filetest/catted.txt: input file output file

i think there @ least 4 things wrong script....

firstly, loop set value of i name of each file in succession, want use i inside loop, this:

for in $*     cat "$i"  ....somewhere done

secondly, if use > redirection, each file land exactly on top of previous one, should use >> redirection append current file end of previous 1 this

for in $*     cat "$i"   >>  ...somewhere done

thirdly, think should use double-quoted "$@" command-line arguments, rather plain $*

for in "$@" ...

fourthly, can achieve exact effect think want simpler command:

cat "$@" > /home/christy/documents/filetest/catted.txt
