I am trying to run
diff <(tar -tvf HIVE_CLIENT.tar.gz | sort) <(tar -tvf YARN_CLIENT.tar.gz | sort)
putting this command inside script, when I execute script it shows error
syntax error near unexpected token `(' "
But when I do not put inside script rather than run from shell directly it works.
Probably your script is run with /bin/sh and not with /bin/bash, but command substitution is a bash feature and not implemented in sh. So I suppose you are using bash as your shell which is why it is working from the command line.
Try adding this prefix to your script, and remove existing shebangs (like #!/bin/sh or similar):
#!/bin/bash
You should try following two actions:
Use #!/bin/bash as your shebang (First line of your script)
This may be needed based on your bash, use only if opetion 1 does not help. Use following commands to flip between posix mode which is needed for process substitution:
set +o posix
diff <(tar -tvf HIVE_CLIENT.tar.gz | sort) <(tar -tvf YARN_CLIENT.tar.gz | sort)
set -o posix
Example:
wc -l <(ls -lrt)
sh: syntax error near unexpected token `('
set +o posix
wc -l <(ls -lrt)
114 /dev/fd/00
set -o posix
wc -l <(ls -lrt)
sh: syntax error near unexpected token `('
