Numerical Calculation Problems

Numerical computing-general Linux technology-Linux technology and application information. For more information, see the following section. Hello everyone, I am executing the following script, so there is a computing problem. Please take a look:
#! /Bin/bash
Dat_dir =./glmis_exp_data
Ctl_dir =./control_file
Log_dir =./log_file
Sed's/| // G' $ dat_dir/glmis_tables_counts.dat | tr A-Z a-z> $ dat_dir/glmis_tables_counts_compare.dat
While read table_line
Do
Table_name = 'echo $ table_line | awk '{print $1}' | tr A-Z a-Z'
Awk '/infile/{print $2}' $ ctl_dir/$ table_name.ctl | sed "s /'. \/glmis_exp_data \ // g "| sed" s /. dat '// g "> ctl_tmp
Glmis_rows = 0
Table_rows = 0
While read table_row
Do
Table_rows = 'awk'/'$ table_row'/{print $2} '$ dat_dir/glmis_tables_counts_compare.dat'
Echo $ glmis_rows
Echo $ table_rows
Glmis_rows = 'expr $ glmis_rows + $ table_rows'
Echo $ glmis_rows
Done Load_row = 'awk'/Rows successfully loaded/{print $1} '$ log_dir/$ table_line.log'
If ["$ glmis_rows"-eq "$ load_row"]; then
Echo "$ table_line: glmis_rows = load_row = $ glmis_rows"
Else
Echo "$ table_line: error"
Fi

Done
The execution result is:

The main problem is the red font.
