I have a foreach loop in a csh script and I noticed that it tries to find the files with the pattern *$searchpt* in the file name. I'm confused as I never specified checking for the files.
#!/bin/bash
foreach x (67402996 67402998)
{
grep -a x FINAL2006.dat >> MISSING_RECORDS.dat
}
I'm trying to pass a list to the variable x, and then grep for that string in FINAL2006.dat...
Final2006.dat is in the same folder as my .sh file. I call this with a .cmd file...
At any rate,... (6 Replies)

I have a simple csh script that has a simple foreach loop that goes over numbers, from 1 to 10:
foreach n(1 2 3 4 5 6 7 8 9 10)

end
Now I want to expand the script to work on over a hundred consecutive n values. Obviously, typing all the numbers between 1 to 100 is an unreasonable... (7 Replies)

I've been using the basic code as follows:
foreach line ("`file.csv`")

Hi
You might find it very trivial but actually don't know how to loop through all sub-directories and their child directories into a csh. bash was easier I believe but here I am, stuck with csh. So elaborately here's my problem:

foreach
foreach(3tcl) Tcl Built-In Commands foreach(3tcl)__________________________________________________________________________________________________________________________________________________NAME
foreach - Iterate over all elements in one or more lists
SYNOPSIS
foreach varname list body
foreach varlist1 list1 ?varlist2 list2 ...? body
_________________________________________________________________DESCRIPTION
The foreach command implements a loop where the loop variable(s) take on values from one or more lists. In the simplest case there is one
loop variable, varname, and one list, list, that is a list of values to assign to varname. The body argument is a Tcl script. For each
element of list (in order from first to last), foreach assigns the contents of the element to varname as if the lindex command had been
used to extract the element, then calls the Tcl interpreter to execute body.
In the general case there can be more than one value list (e.g., list1 and list2), and each value list can be associated with a list of
loop variables (e.g., varlist1 and varlist2). During each iteration of the loop the variables of each varlist are assigned consecutive
values from the corresponding list. Values in each list are used in order from first to last, and each value is used exactly once. The
total number of loop iterations is large enough to use up all the values from all the value lists. If a value list does not contain enough
elements for each of its loop variables in each iteration, empty values are used for the missing elements.
The break and continue statements may be invoked inside body, with the same effect as in the for command. Foreach returns an empty string.
EXAMPLES
This loop prints every value in a list together with the square and cube of the value:
set values {1 3 5 7 2 4 6 8} ;# Odd numbers first, for fun!
puts "Value Square Cube" ;# Neat-looking header
foreach x $values { ;# Now loop and print...
puts " $x [expr {$x**2}] [expr {$x**3}]"
}
The following loop uses i and j as loop variables to iterate over pairs of elements of a single list.
set x {}
foreach {i j} {a b c d e f} {
lappend x $j $i
}
# The value of x is "b a d c f e"
# There are 3 iterations of the loop.
The next loop uses i and j to iterate over two lists in parallel.
set x {}
foreach i {a b c} j {d e f g} {
lappend x $i $j
}
# The value of x is "a d b e c f {} g"
# There are 4 iterations of the loop.
The two forms are combined in the following example.
set x {}
foreach i {a b c} {j k} {d e f g} {
lappend x $i $j $k
}
# The value of x is "a d e b f g c {} {}"
# There are 3 iterations of the loop.
